From 8544942048ee74b7d92e47f10222f8840fd8c725 Mon Sep 17 00:00:00 2001 From: Nick Schrock Date: Mon, 13 Aug 2018 05:56:03 -0700 Subject: [PATCH 001/103] Execution Rewrite: The Compute Node This is a substantial rewrite of the execution pipeline and will open up a whole new range of explorations and more. The core architectural change here is that there is an entire new system of representation for the *execution* graph of computations (compute nodes) rather than just the PipelineDefintion. The compute node graph is constructed from the PipelineDefinition and input config. A number of things happen during this construction: 1. All sources, materializations, expectations, and transforms are modelled within the same abstraction: the compute node. All argument checking and validiations are done during compute node graph construction time, before any execution proceeds. This is similar to validation as a separate step in the graphql universe. 2. Compute nodes can have multiple inputs, multiple outputs, and a configuration dictionary (arg dict). This allows for maximum flexibility and for it to be generic enough to handled the different concepts listed in bullet 1. For example a source is just a compute node with *no* inputs, a single output, and an arg dict. A materialization is a compute node with an input (coming from the output of of a transform), no outputs, and an arg dict. A transform can have multiple inputs and (now) multiple outputs, but it current doesn't support an arbitrary arg dict. Expectations are also a compute node. 3. This will allow for dynamically configured dependencies as opposed to the more static construction. We are already using the dynamic compute node graph to change based on policy. If, for example, you do turn off expectations those compute nodes are never even constructed. If they are they dynamically placed before the appopriate input or after the appropriate output and set up to execute in parallel. 4. Sources and materializationsn as separate concepts are going to largely dissappears. I am still toying with how to expose them to the higher level config and pipeline definition API, but if they exist they will be largely symbolic. 5. More sophisticated expectations execution will happen via this mechanism. For example I fully anticipate that expectation compute nodes will have two outputs, one for the value being tested and passed through, but the other for the expectation result. This will allow the framework (or the user in some capacity) to add compute nodes that act on the expectation. 6. Composability: This is also an interesting angle for putting composability into this execution engine. It should be totally possible to build "composite" compute nodes that consist of a DAG of compute nodes. When taken as a whole they will have a set of inputs, a set of outputs, and a set of configuration. 7. Visualizations and debugging: This will be a powerful tool of visualization and debugging. One will be able to set config, apply it to a pipeline, and previz *exactly* what is going to execute in a very granular way. Execution should be able to be reported through this mechanism as well. Next up I'm going to leverage this architectural change to change the dependency API for pipeline definitions. --- python_modules/Makefile | 14 + .../dagster_ge_tests/test_pandas_ge.py | 46 +- python_modules/dagster/dagster/__init__.py | 26 +- .../dagster/dagster/check/__init__.py | 6 +- .../dagster/dagster/cli/pipeline.py | 13 +- python_modules/dagster/dagster/config.py | 4 +- .../dagster/dagster/core/compute_nodes.py | 891 ++++++++++++++++++ .../core/core_tests/test_compute_nodes.py | 83 ++ .../core/core_tests/test_core_execution.py | 208 ---- .../core/core_tests/test_error_handling.py | 59 -- .../core/core_tests/test_execute_solid.py | 16 +- .../core_tests/test_input_expectations.py | 100 -- .../core/core_tests/test_naming_collisions.py | 30 +- .../core_tests/test_output_expectations.py | 73 -- .../core/core_tests/test_pipeline_errors.py | 9 +- .../core_tests/test_pipeline_execution.py | 123 +-- .../core/core_tests/test_pipeline_meta.py | 5 -

Instead, this moves that concept to a Python API called the repository. A repository is a collection of pipelines. Instead of specifying every pipeline in a project individually in a yaml file, we now just have a single repository. The repository object creates pipelines on demand (so that they can be loaded by name without loading all the pipelines). Repositories *also* have the concept of library solids (which can be thought of higher order solids) which are ways to create solids in a config-driven way. Authors will be able to design library solids that are resuable. This will enable a layer of solid creation via config, and much easier testing because authors will be able to inject pre-made solids into existing pipelines to stub out values. --- python_modules/dagit/dagit/app.py | 38 ++++- python_modules/dagit/dagit/cli.py | 40 ++--- python_modules/dagit/dagit/schema.py | 12 +- python_modules/dagster/dagster/__init__.py | 3 + .../dagster/dagster/check/__init__.py | 21 ++- .../dagster/check/check_tests/test_check.py | 4 + .../dagster/dagster/cli/__init__.py | 25 +-- python_modules/dagster/dagster/cli/context.py | 83 ---------- .../dagster/dagster/cli/pipeline.py | 77 +++++---- .../dagster/dagster/cli/repository_config.py | 76 +++++++++ .../dagster/dagster/core/argument_handling.py | 53 +++++- .../core/core_tests/test_library_solids.py | 51 ++++++ .../core_tests/test_repository_definition.py | 112 +++++++++++++ .../dagster/dagster/core/definitions.py | 152 +++++++++++------- .../dagster/dagster_examples/pipelines.yml | 5 - .../dagster/dagster_examples/repository.py | 9 ++ .../dagster/dagster_examples/repository.yml | 3 + python_modules/dagster/dagster/graphviz.py | 8 +- python_modules/dagster/setup.py | 2 +- 19 files changed, 523 insertions(+), 251 deletions(-) delete mode 100644 python_modules/dagster/dagster/cli/context.py create mode 100644 python_modules/dagster/dagster/cli/repository_config.py create mode 100644 python_modules/dagster/dagster/core/core_tests/test_library_solids.py create mode 100644 python_modules/dagster/dagster/core/core_tests/test_repository_definition.py delete mode 100644 python_modules/dagster/dagster/dagster_examples/pipelines.yml create mode 100644 python_modules/dagster/dagster/dagster_examples/repository.py create mode 100644 python_modules/dagster/dagster/dagster_examples/repository.yml diff --git a/python_modules/dagit/dagit/app.py b/python_modules/dagit/dagit/app.py index 2a4b2f1f370e4..949dd45becfc3 100644 --- a/python_modules/dagit/dagit/app.py +++ b/python_modules/dagit/dagit/app.py @@ -4,16 +4,44 @@ from flask_graphql import GraphQLView from flask_cors import CORS +from dagster import check +from dagster.cli.repository_config import ( + RepositoryInfo, + reload_repository_info, +) + from .schema import create_schema +class RepositoryContainer: + ''' + This class solely exists to implement reloading semantics.

This is, IMO, a much more sound system of managing config. Instead of having "argument dictionaries" everywhere, configs take a top level type to describe themselves. I've implemented one composite type, the accepts a set of Fields and then produced a python dict for implementors to process at runtime. This system has a number of advantages: 1) Configs can be arbitrarily nested and grouped together. This already would have been immediately useful. 2) We can move to strongly-typed APIs for configs. Instead of vending a dict, vend a namedtuple, for example. 3) Even further that 2) this is a step towards a formalized "resource" pattern for configs. Instead of the type producing a dumb struct, you could imagine the config producing a richer "resource" object that manages connections or so forth. Or alternatively a system stacked on top of this one that does that (and requires configs of a certain type). 4) This sets up the ability to support single value config quite easily. I'm not sure if this is a good idea, but it is possible now if we allow it. One clear deficiency is a regression of error messaging. However, we weren't testing error messages properly the entire time! (see https://github.com/dagster-io/dagster/issues/135) So we need to go through and audit type-system-related errors and figure out a way to construct them in this new structure. --- python_modules/.pylintrc | 3 +- python_modules/.vscode/settings.json | 6 +- python_modules/dagster/dagster/__init__.py | 5 +- .../dagster/dagster/cli/pipeline.py | 12 +- .../dagster/dagster/core/argument_handling.py | 120 ------- .../dagster/dagster/core/compute_nodes.py | 34 +- .../core/core_tests/test_argument_handling.py | 151 -------- .../core/core_tests/test_compute_nodes.py | 7 +- .../core_tests/test_config_type_system.py | 322 ++++++++++++++++++ .../core/core_tests/test_custom_context.py | 87 +++-- .../core/core_tests/test_library_solids.py | 51 --- .../core/core_tests/test_naming_collisions.py | 6 +- .../core/core_tests/test_pipeline_errors.py | 4 +- .../core_tests/test_repository_definition.py | 51 --- .../core/core_tests/test_solid_with_config.py | 10 +- .../dagster/dagster/core/decorators.py | 4 +- .../dagster/dagster/core/definitions.py | 158 ++++----- .../dagster/dagster/core/execution.py | 28 +- python_modules/dagster/dagster/core/types.py | 179 +++++++++- .../test_sql_project_pipeline.py | 30 +- .../dagster/dagster/pandas/__init__.py | 14 +- ...est_pandas_hello_world_no_library_slide.py | 10 +- .../sqlalchemy_tests/test_basic_solid.py | 7 +- .../test_isolated_sql_tests.py | 7 +- .../test_isolated_templated_sql_tests.py | 7 +- .../subquery_builder_experimental.py | 6 +- .../dagster/dagster/sqlalchemy/templated.py | 8 +- python_modules/dagster/setup.py | 2 +- 28 files changed, 722 insertions(+), 607 deletions(-) delete mode 100644 python_modules/dagster/dagster/core/argument_handling.py delete mode 100644 python_modules/dagster/dagster/core/core_tests/test_argument_handling.py create mode 100644 python_modules/dagster/dagster/core/core_tests/test_config_type_system.py delete mode 100644 python_modules/dagster/dagster/core/core_tests/test_library_solids.py diff --git a/python_modules/.pylintrc b/python_modules/.pylintrc index 436d7504aa8d0..92eca9f71c415 100644 --- a/python_modules/.pylintrc +++ b/python_modules/.pylintrc @@ -20,4 +20,5 @@ # R1705 Unnecessary else after return # R0902 Too many instance attributes.

This process goes by many names -- ETL (extract-load-transform), ELT (extract-transform-load), model production, data integration, and so on -- but in essence they all describe the same activity: Performing a set of computations structured as a DAG (directed, acyclic graph) that end up producing data assets, whether those assets be tables, files, machine-learning models, etc. + +There are a few tools in this repo + +This repo has a few primary components: + +- **Dagster**: The core programming model and abstraction stack; a stateless single-node and -process execution engine; and a CLI tool for driving that engine. +* **Dagit**: Dagit is a rich viewer for Dagster assets. +* **Dagster GE**: A Dagster integration with Great Expectations. (see https://github.com/great-expectations/great_expectations) + +------------------- +Opinions and Values +------------------- + +As noted above Dagster has a point of view and values regarding how data pipelines should be built and structured. We list them in no particular order: + +* **Functional Data Pipelines**: We believe that data pipelines should be organized as DAGs of functional, idempotent computations. These computations injest input, do computation, and produce output, either with no side effects or well-known, un-externalized side effects. Given the same inputs and configuration, the computation should always produce the same output. These computations should also be parameterizable, so that they can execute in different environments. See https://bit.ly/2LxDgnr for an excellent overview of functional programing in batch computations. +* **Self-describing**: Pipelines should be self-describing with rich metadata and types. Users should be able to approach a pipeline, and use tooling to inspect the pipelines for their structure and capabilities. This metadata should be co-located with actual code of the pipeline. Documentation and code is delivered as a single artifact. +* **Compute-agnostic**: Dagster has opinions about the structure and best practices of data pipelines. It has no opinions about what libraries and engines use to do actual compute. The core computation within a dagster pipeline is user-specified code, meaning that it could be anything: Pandas, Spark, SQL computations on a data warehouse, vanilla python, or any combination therein. +* **Testable by design and by default**: Testing data pipelines is notoriously difficult. Because it is so difficult it is often never done, or done poorly. Dagster pipelines are designed to be tested. They have explicit support for pipeline authors to manage and maintain multiple operating environments -- for example, unit testing, integration testing, and production environments, among others. In addition dagster can execute arbitrary subsets and nodes of the pipeline, critical testability. (This capability happens to be useful in operational contexts as well). +* **First-class data quality tests**: Testing code is important in data pipelines, but it is not sufficient. Data quality tests -- run during every meaningful stage of production -- are critical to reduce the maintenance burden of data pipelines. Pipeline authors generally do not have control of their input data, and make many implicit assumptions about that data. The data formats can also change over time. In order to control this entropy, Dagster encourages users to computationally verify assumptions (known as expectations) about the data as part of the piplien process. This way if those assumptions are broken, the breakage can be reported quickly, easily, and with rich metadata and diagnostic information. These expectations can also serve as contracts between teams. See https://bit.ly/2mxDS1R for a primer on pipeline tests for data quality. +* **Gradual, optional typing**: Dagster contains a type system to describe the values flowing through the pipeline. This allows nodes in a pipeline know if they are compatible before execution, and serves as value documentation and runtime error checking. + + +The core abstraction in Dagster is a *solid*, a logical unit of computation in a data pipeline. At its core a solid is a configurable function that accepts abstract inputs and produces outputs. + +* Inputs: +* Outputs: +* Configuration: +* Transform: + +Inputs are things. + +* Name: +* Type: +* Expectations: + +Outputs are things: + +* Name +* Type +* Expectations + +Solids are group together in *pipelines*. Pipelines are comprised of: + +* Solids +* Dependencies +* Context Definitions + + + +Solid formally separates the notion of inputs, outputs, the core transform. The core goal of this is cleanly and clearly separate the domain logic of each transform and its operational environments. This allows solids or pipelines of solids to easily be executable in a number of environments: unit-testing, local development, integration tests, CI/CD, staging environments, production environments, and so on and so forth. + +Alongside with the core abstraction, Dagster provides helpers to create Solids that operate on Pandas dataframes and SQL databases. + +Example +------- + + + +.. code-block:: python + + + import pandas as pd + import dagster.core + from dagster.core.definitions import ( + InputDefinition, + OutputDefinition + ) + from dagster.core.decorators import ( + solid, + ) + + # Solids can be created by annotating transform function with + # a decorator + @solid( + # Solid inputs define arguments passed to transform function + inputs=[ + InputDefinition( + name='num', + + ) + ], + # Solid output determines what solid should return. + output=OutputDefinition(materializations=[ + dataframe_to_csv_materialization, + ]) + ) + def sum_solid(num): + sum_df = num.copy() + # Here we add a new column to dataframe to sum up num1 and + # num2 columns + sum_df['sum'] = sum_df['num1'] + sum_df['num2'] + return sum_df + + + @solid( + inputs=[ + InputDefinition(name="sum") + ], + output=OutputDefinition(materializations=[ + dataframe_to_csv_materialization, + ]) + ) + def sum_sq_solid(sum): + sum_sq = sum.copy() + sum_sq['sum_sq'] = sum['sum']**2 + return sum_sq + + + # After definining a solid, we are grouping them into a pipeline + pipeline = dagster.core.pipeline( + name='pandas_hello_world', + solids=[ + sum_solid, + sum_sq_solid, + ], + ) + +You might notice that there is no actual CSV file specified as inputs. This is because such parameters are passed in environment. This allows you to customize it in runtime. To run your solid, we'll pass that environment to the execution function. + +.. code-block:: python + + pipeline_result = dagster.execute_pipeline(pipeline, environment) + + +We can simplify the above example by using built-in dagster pandas inputs and outputs. + +.. code-block:: python + + # TODO updated example definition + +We can specify in order to get artifacts for the results. We can materialize output from any solid, this can be useful to see if intermediate results make sense. + +.. code-block:: python + + # TODO updated example config driving + +Dagster CLI +=========== + +In addition to programmatic API, you can also use dagster CLI to run the pipelines. In that case the environment is specified through yaml configuration files. + +The folder structure should be as follows. + +.. code-block + + pipeline_project_name/ + pipelines.yml + pipeline_module_1/ + env.yml + pipeline_module_2/ + env.yml + +Pipelines yml specify the pipelines that are present in current project. Env specifies environment for each particular pipeline. + +.. code-block:: yaml + + # TODO pipelines file + +.. code-block:: yaml + + # TODO example config file + + +.. code-block:: sh + +# TODO example CLI driving + + +Concepts +======== + +Transform +--------- + +This is core, user-defined transform that performs the logical data +computation. In this case the transform is ``hello_world_transform_fn`` +and it is passed as parameter into the solid. It takes one or more +inputs and produces an output. All other concepts in a solid are the +metadata and structure that surround this core computation + +Inputs +--------- + +For each argument to the transform function, there is one +``InputDefinition`` object. It has a name, which must match the +parameters to the transform function. The input definitions define a +name, a dependency for the input (what upstream solid produces its +value, see below) and a number of sources. An input definition must +specify at least a dependency or a source. The input can have any number +of sources. + + +Output +--------- + +The ``OutputDefinition`` represents the output of the transform +function. + + + +Higher-level APIs +------------------ + +# TODO keep this section? + +Execution +--------- + +These are useless without being able to execute them. In order to +execute a solid, you need to package it up into a pipeline. + +.. code-block:: python + + pipeline = dagster.PipelineDefinition(name='hello_world', solids=[sum_solid]) + +Then you an execute it by providing an environment. You must provide +enough source data to create all the inputs necessary for the pipeline. + +.. code-block:: python + + environment = config.Environment( + sources={ + 'sum' : { + 'num_df' : config.Source(name='CSV', args={'path': 'path/to/input.csv'}) + } + } + ) + + pipeline_result = dagster.execute_pipeline( + dagster.ExecutionContext(), + pipeline, + environment + ) + + print(pipeline_result.result_for_solid('sum').transformed_value) + + +Dependencies +------------ + +So far we have demonstrated a single stage pipeline, which is obviously +of limited value. + +Imagine we wanted to add another stage which took the sum we produced +and squared that value. (Fancy!) + +.. code-block:: python + + # TODO example dependencies + +Note that input specifies that dependency. This means that the input +value passed to the transform can be generated by an upstream dependency +OR by an external source. This allows for the solid to be executable in +isolation or in the context of a pipeline. + +.. code-block:: python + + # TODO example driving + +The above executed both solids, even though one input was provided. The +input into sum\_sq\_solid was provided by the upstream result from the +output of sum\_solid. + +You can also execute subsets of the pipeline. Given the above pipeline, +you could specify that you only want to specify the first solid: + +.. code-block:: python + + # TODO example subdag execution + + + +Expectations +------------ + +Expectations are another reason to introduce logical seams between data +computations. They are a way to perform data quality tests or +statistical process control on data pipelines. diff --git a/assets/Dagster.png b/assets/Dagster.png new file mode 100644 index

helps you organize, run and test your data processing pipelines. Instead of writing ad-hoc data processing script, Dagster encourages separating data input, data processing and data output, as well as separating your processing in several steps. - - -The core abstraction in Dagster is a **Solid**, a logical unit of computation in a data pipeline. At its core a Solid is a coarse-grained pure function. It takes multiple inputs, performs a computation, produces an output. Inputs can either be received from outputs from upstream solids in the pipeline or external sources (e.g. files). Likewise, outputs from the transform can either be flowed to downstream solids or materialized (e.g. to a file in an object store) so that it can be inspected or accessed by an external system. - -Solid formally separates the notion of inputs, outputs, the core transform. The core goal of this is cleanly and clearly separate the domain logic of each transform and its operational environments. This allows solids or pipelines of solids to easily be executable in a number of environments: unit-testing, local development, integration tests, CI/CD, staging environments, production environments, and so on and so forth. - -Alongside with the core abstraction, Dagster provides helpers to create Solids that operate on Pandas dataframes and SQL databases. - -Example -------- - - - -.. code-block:: python - - - import pandas as pd - import dagster.core - from dagster.core.definitions import ( - InputDefinition, - OutputDefinition - ) - from dagster.core.decorators import ( - solid, - source, - materialization, - ) - - # Sources define *how* to get data.

In this case the transform is ``hello_world_transform_fn`` -and it is passed as parameter into the solid. It takes one or more -inputs and produces an output. All other concepts in a solid are the -metadata and structure that surround this core computation - -Inputs ---------- - -For each argument to the transform function, there is one -``InputDefinition`` object. It has a name, which must match the -parameters to the transform function. The input definitions define a -name, a dependency for the input (what upstream solid produces its -value, see below) and a number of sources. An input definition must -specify at least a dependency or a source. The input can have any number -of sources. - -Sources -^^^^^^^ - -Sources are the the way that one can create an input to a transform from -external resources. A source is a function that takes a set of arguments -and produces a value that is passed to the transform for processing. In -this case, a CSV file is the only source type. One can imagine adding -other source types to create pandas dataframes for Json, Parquet, and so -forth. End users will typically rely on pre-existing libraries to -specify sources. - -Sources also declare what arguments they expect. These are inspectable -and could be used to render information for web or command line tools, -to verify the validity of confie files, and other tooling contexts. The -framework verifies when solids or pipelines of solids are executed, that -the arguments abide by the declaration. These arguments are then sent to -the source function in the ``arg_dict`` parameter. - -Output ---------- - -The ``OutputDefinition`` represents the output of the transform -function. - -Materializations -^^^^^^^^^^^^^^^^ - -Materializations are the other end of source. This specifies the way the -output of a transform can be materialized. In this example which uses -pandas dataframes, the sources and materializations will be symmetrical. -In the above example we specified a single materialization, a CSV. One -could expand this to include JSON, Parquet, or other materialiations as -appropriate. - -However in other contexts that might be true. Take solids that operate -on SQL-based data warehouses or similar. The core transform would be the -SQL command, but the materialization would specify a -``CREATE TABLE AS``, a table append, or a partition creation, as -examples. - -Higher-level APIs ------------------- - -These definitions will typically be composed with higher level APIs. For -example, the above solid could be expressed using APIs provided by the -pandas kernel. (Note: the "kernel" terminology is not settled) - -.. code-block:: python - - import dagster - import dagster.pandas as dagster_pd - - def sum_transform(num_df): - num_df['sum'] = num_df['num1'] + num_df['num2'] - return num_df - - sum_solid = SolidDefinition.single_output_transform( - name='sum', - description='This computes the sum of two numbers.' - inputs=[dagster_pd.dataframe_csv_input(name='num_df')], - transform_fn=sum_transform, - output=dagster_pd.dataframe_output(), - ) - -Execution ---------- - -These are useless without being able to execute them. In order to -execute a solid, you need to package it up into a pipeline. - -.. code-block:: python - - pipeline = dagster.PipelineDefinition(name='hello_world', solids=[sum_solid]) - -Then you an execute it by providing an environment. You must provide -enough source data to create all the inputs necessary for the pipeline. - -.. code-block:: python - - environment = config.Environment( - sources={ - 'sum' : { - 'num_df' : config.Source(name='CSV', args={'path': 'path/to/input.csv'}) - } - } - ) - - pipeline_result = dagster.execute_pipeline( - dagster.ExecutionContext(), - pipeline, - environment - ) - - print(pipeline_result.result_for_solid('sum').transformed_value) - -Execute pipeline does a purely in-memory transform, materializing -nothing. This is useful in testing and CI/CD contexts. - -Materialization ----------------- - -In order to produce outputs that are available to external systems, you -must materialize them.

We list them in no particular order: + +Functional +^^^^^^^^^^ +We believe that data pipelines should be organized as DAGs of functional, idempotent computations. +These computations injest input, do computation, and produce output, either with no side effects +or well-known, un-externalized side effects. Given the same inputs and configuration, the +computation should always produce the same output. These computations should also be +parameterizable, so that they can execute in different environments. + + * See https://bit.ly/2LxDgnr for an excellent overview of functional programing in batch computations. + +Self-describing +^^^^^^^^^^^^^^^ +Pipelines should be self-describing with rich metadata and types. Users should be able to approach +a pipeline, and use tooling to inspect the pipelines for their structure and capabilities. This +metadata should be co-located with actual code of the pipeline. Documentation and code is delivered +as a single artifact. + +Compute-agnostic +^^^^^^^^^^^^^^^^ +Heterogeneity in data pipelines is the norm, rather than the exception. Data pipelines are written +by many people in different personas -- data engineers, machine-learning engineers, data +scientists, analysts and so on -- who have different needs and tools, and are particular about +those tools. + +Dagster has opinions about the structure and best practices of data pipelines. It has no opinions +about what libraries and engines use to do actual compute. Dagster pipelines can be comprised of +any python computation, which could be Pandas, Spark, or it could in turn invoke SQL or any +other DSL or library deemed appropriate to the task. + +Testable +^^^^^^^^ +Testing data pipelines is notoriously difficult. Because it is so difficult it is often never +done, or done poorly. Dagster pipelines are designed to be tested. They have explicit support +for pipeline authors to manage and maintain multiple operating environments -- for example, unit +testing, integration testing, and production environments, among others. In addition dagster can +execute arbitrary subsets and nodes of the pipeline, critical testability. (This capability +happens to be useful in operational contexts as well). + +Verifiable data quality +^^^^^^^^^^^^^^^^^^^^^^^ +Testing code is important in data pipelines, but it is not sufficient. Data quality tests -- run +during every meaningful stage of computation in production -- are critical to reduce the +maintenance burden of data pipelines. Pipeline authors generally do not have control of their +input data, and make many implicit assumptions about that data. The data formats can also change +over time. In order to control this entropy, Dagster encourages users to computationally verify +assumptions (known as expectations) about the data as part of the piplien process. This way if +those assumptions are broken, the breakage can be reported quickly, easily, and with rich metadata +and diagnostic information. These expectations can also serve as contracts between teams. + + * See https://bit.ly/2mxDS1R for a primer on pipeline tests for data quality. + +Gradual, optional typing +^^^^^^^^^^^^^^^^^^^^^^^^ + +Dagster contains a type system to describe the values flowing through the pipeline and the +configuration of the pipeline. This allows nodes in a pipeline know if they are properly +arranged and configuration prior to execution before execution, and serves as value +documentation and runtime error checking. diff --git a/python_modules/dagster/docs/topic_guides.rst b/python_modules/dagster/docs/topic_guides.rst new file mode 100644 index 0000000000000..e69de29bb2d1d diff --git a/python_modules/dagster/docs/tutorials.rst b/python_modules/dagster/docs/tutorials.rst new file mode 100644 index 0000000000000..e69de29bb2d1d From dc41f7136dd68df29808e74640fd67c7a43b811a Mon Sep 17 00:00:00 2001 From: Mikhail Novikov Date: Thu, 6 Sep 2018 11:33:34 +0300 Subject: [PATCH 053/103] Fixed wrong type reference --- python_modules/dagit/dagit/webapp/src/TypeWithTooltip.tsx | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/python_modules/dagit/dagit/webapp/src/TypeWithTooltip.tsx b/python_modules/dagit/dagit/webapp/src/TypeWithTooltip.tsx index fc1186758df95..ad25f65650d09 100644 --- a/python_modules/dagit/dagit/webapp/src/TypeWithTooltip.tsx +++ b/python_modules/dagit/dagit/webapp/src/TypeWithTooltip.tsx @@ -2,10 +2,10 @@ import * as React from "react";

Takes inputs. No config or context. Produces a single output. Only return naked value out of the transform. 2) solids. Takes inputs, produces outputs. Accepts context and config. The transform can return a naked value, a Result, or a generator that yields a sequence of Results. This satisfies the need/desire for "simple" and introductory use cases for solids (in the form of a lambda_solid) relatively elegantly but then has a decorator-style solid that can cover nearly all use cases. --- .../dagster_ge_tests/test_pandas_ge.py | 14 +- python_modules/dagster/dagster/__init__.py | 2 + .../core/core_tests/test_compute_nodes.py | 10 +- .../core/core_tests/test_custom_context.py | 41 ++-- .../core/core_tests/test_decorators.py | 118 +++++++---- .../dagster/dagster/core/decorators.py | 190 +++++++++++++++--- .../dagster/dagster/core/definitions.py | 2 +- .../pandas_hello_world/pipeline.py | 20 +- .../test_pandas_hello_world_library_slide.py | 8 +- .../pandas/pandas_tests/test_pandas_solids.py | 20 +- .../pandas_tests/test_pandas_user_error.py | 13 +- .../dagster/docs/apidocs/decorators.rst | 2 + python_modules/dagster/setup.py | 2 +- 13 files changed, 295 insertions(+), 147 deletions(-) diff --git a/python_modules/dagster-ge/dagster_ge_tests/test_pandas_ge.py b/python_modules/dagster-ge/dagster_ge_tests/test_pandas_ge.py index 52db733479761..3ac6035293bc1 100644 --- a/python_modules/dagster-ge/dagster_ge_tests/test_pandas_ge.py +++ b/python_modules/dagster-ge/dagster_ge_tests/test_pandas_ge.py @@ -9,7 +9,7 @@ PipelineDefinition, config, execute_pipeline, -

You can run tests for python by running `tox` in `python_modules/dagit` or `python_modules/dagster`. + +7. Inside webapp directory, you can run tests too. `yarn test` runs all tests. In development it's handy to run `yarn run jest --watch` to have interactive test runner. + +8. Some webapp tests use *snapshots* - auto-generated results to which the test render tree is compared. Those tests are supposed to break when you change something, check that the change is sensible and run `yarn run jest -u` to update snapshot to the new result. You can also update snapshots interactively when you are in `--watch` mode. diff --git a/python_modules/dagit/dagit/webapp/jest/fileTransformer.js b/python_modules/dagit/dagit/webapp/jest/fileTransformer.js new file mode 100644 index 0000000000000..cc01d2859953c --- /dev/null +++ b/python_modules/dagit/dagit/webapp/jest/fileTransformer.js @@ -0,0 +1,8 @@ +// fileTransformer.js +const path = require("path"); + +module.exports = { + process(src, filename, config, options) { + return "module.exports = " + JSON.stringify(path.basename(filename)) + ";"; + } +}; diff --git a/python_modules/dagit/dagit/webapp/package.json b/python_modules/dagit/dagit/webapp/package.json index 456dd7d09db4e..771d3a6a171c1 100644 --- a/python_modules/dagit/dagit/webapp/package.json +++ b/python_modules/dagit/dagit/webapp/package.json @@ -51,27 +51,22 @@ "start": "react-scripts-ts start", "build": "react-scripts-ts build", "eject": "react-scripts-ts eject", - "test": "npm run ts && npm run jest", + "prettier": "prettier --write \"./src/**/*.tsx\"", + "test": "npm run ts && npm run jest && npm run check-prettier", "jest": "jest", + "check-prettier": "prettier --list-different \"./src/**/*.tsx\"", "ts": "tsc -p .", "download-schema": "apollo schema:download --endpoint $REACT_APP_GRAPHQL_URI ./src/schema.json", "generate-types": "apollo codegen:generate --queries \"./src/**/*.tsx\" --target typescript types --schema ./src/schema.json", "watch-types": "apollo codegen:generate --queries \"./src/**/*.tsx\" --target typescript types --schema ./src/schema.json --watch" }, "jest": { - "roots": [ - "/src" - ], + "roots": ["/src"], "transform": { - "^.+\\.(ts|tsx)$": "ts-jest" + "^.+\\.(ts|tsx)$": "ts-jest", + "\\.(jpg|jpeg|png|gif|eot|otf|webp|svg|ttf|woff|woff2|mp4|webm|wav|mp3|m4a|aac|oga)$": "/jest/fileTransformer.js" }, - "moduleFileExtensions": [ - "js", - "jsx", - "json", - "ts", - "tsx" - ], + "moduleFileExtensions": ["js", "jsx", "json", "ts", "tsx"], "testRegex": "/__tests__/.*\\.test\\.(ts|tsx)$", "testURL": "http://localhost" } diff --git a/python_modules/dagit/dagit/webapp/public/index.html b/python_modules/dagit/dagit/webapp/public/index.html index 4c5e3649ff206..f7a264f59d666 100644 --- a/python_modules/dagit/dagit/webapp/public/index.html +++ b/python_modules/dagit/dagit/webapp/public/index.html @@ -5,6 +5,7 @@ + + + + + Dagit diff --git a/python_modules/dagit/dagit/webapp/src/Config.tsx b/python_modules/dagit/dagit/webapp/src/Config.tsx index 7b4dca300404b..a2fb22eabdc23 100644 --- a/python_modules/dagit/dagit/webapp/src/Config.tsx +++ b/python_modules/dagit/dagit/webapp/src/Config.tsx @@ -1,7 +1,7 @@ import * as React from "react"; import gql from "graphql-tag"; import styled from "styled-components"; -import { UL, H6 } from "@blueprintjs/core"; +import { UL, H6, Colors } from "@blueprintjs/core"; import SpacedCard from "./SpacedCard"; import TypeWithTooltip from "./TypeWithTooltip"; import Description from "./Description"; @@ -78,5 +78,7 @@ const ConfigCard = styled(SpacedCard)` const DescriptionWrapper = styled.div` max-width: 400px; + margin-top: 10px; margin-bottom: 10px; + color: ${Colors.GRAY2}; `; diff --git a/python_modules/dagit/dagit/webapp/src/Description.tsx b/python_modules/dagit/dagit/webapp/src/Description.tsx index 4cd9a0f46d9a7..7426ec9ce12e2 100644 --- a/python_modules/dagit/dagit/webapp/src/Description.tsx +++ b/python_modules/dagit/dagit/webapp/src/Description.tsx @@ -8,15 +8,117 @@ interface IDescriptionProps { description: string | null; } +interface IDescriptionState { + hasMore: boolean; + expanded: boolean; +} + +const MaxHeight = 320; + +/* +If `input` begins with whitespace and every line contains at least that whitespace, +it removes it.

(see https://github.com/great-expectations/great_expectations) -------------------- -Opinions and Values -------------------- - -As noted above Dagster has a point of view and values regarding how data pipelines should be built and structured. We list them in no particular order: - -* **Functional Data Pipelines**: We believe that data pipelines should be organized as DAGs of functional, idempotent computations. These computations injest input, do computation, and produce output, either with no side effects or well-known, un-externalized side effects. Given the same inputs and configuration, the computation should always produce the same output. These computations should also be parameterizable, so that they can execute in different environments. See https://bit.ly/2LxDgnr for an excellent overview of functional programing in batch computations. -* **Self-describing**: Pipelines should be self-describing with rich metadata and types. Users should be able to approach a pipeline, and use tooling to inspect the pipelines for their structure and capabilities. This metadata should be co-located with actual code of the pipeline. Documentation and code is delivered as a single artifact. -* **Compute-agnostic**: Dagster has opinions about the structure and best practices of data pipelines. It has no opinions about what libraries and engines use to do actual compute. The core computation within a dagster pipeline is user-specified code, meaning that it could be anything: Pandas, Spark, SQL computations on a data warehouse, vanilla python, or any combination therein. -* **Testable by design and by default**: Testing data pipelines is notoriously difficult. Because it is so difficult it is often never done, or done poorly. Dagster pipelines are designed to be tested. They have explicit support for pipeline authors to manage and maintain multiple operating environments -- for example, unit testing, integration testing, and production environments, among others. In addition dagster can execute arbitrary subsets and nodes of the pipeline, critical testability. (This capability happens to be useful in operational contexts as well). -* **First-class data quality tests**: Testing code is important in data pipelines, but it is not sufficient. Data quality tests -- run during every meaningful stage of production -- are critical to reduce the maintenance burden of data pipelines. Pipeline authors generally do not have control of their input data, and make many implicit assumptions about that data. The data formats can also change over time. In order to control this entropy, Dagster encourages users to computationally verify assumptions (known as expectations) about the data as part of the piplien process. This way if those assumptions are broken, the breakage can be reported quickly, easily, and with rich metadata and diagnostic information. These expectations can also serve as contracts between teams. See https://bit.ly/2mxDS1R for a primer on pipeline tests for data quality. -* **Gradual, optional typing**: Dagster contains a type system to describe the values flowing through the pipeline. This allows nodes in a pipeline know if they are compatible before execution, and serves as value documentation and runtime error checking. - - -The core abstraction in Dagster is a *solid*, a logical unit of computation in a data pipeline. At its core a solid is a configurable function that accepts abstract inputs and produces outputs. - -* Inputs: -* Outputs: -* Configuration: -* Transform: - -Inputs are things. - -* Name: -* Type: -* Expectations: - -Outputs are things: - -* Name -* Type -* Expectations - -Solids are group together in *pipelines*. Pipelines are comprised of: - -* Solids -* Dependencies -* Context Definitions - - - -Solid formally separates the notion of inputs, outputs, the core transform. The core goal of this is cleanly and clearly separate the domain logic of each transform and its operational environments. This allows solids or pipelines of solids to easily be executable in a number of environments: unit-testing, local development, integration tests, CI/CD, staging environments, production environments, and so on and so forth. - -Alongside with the core abstraction, Dagster provides helpers to create Solids that operate on Pandas dataframes and SQL databases. - -Example -------- - - - -.. code-block:: python - - - import pandas as pd - import dagster.core - from dagster.core.definitions import ( - InputDefinition, - OutputDefinition - ) - from dagster.core.decorators import ( - solid, - ) - - # Solids can be created by annotating transform function with - # a decorator - @solid( - # Solid inputs define arguments passed to transform function - inputs=[ - InputDefinition( - name='num', - - ) - ], - # Solid output determines what solid should return. - output=OutputDefinition(materializations=[ - dataframe_to_csv_materialization, - ]) - ) - def sum_solid(num): - sum_df = num.copy() - # Here we add a new column to dataframe to sum up num1 and - # num2 columns - sum_df['sum'] = sum_df['num1'] + sum_df['num2'] - return sum_df - - - @solid( - inputs=[ - InputDefinition(name="sum") - ], - output=OutputDefinition(materializations=[ - dataframe_to_csv_materialization, - ]) - ) - def sum_sq_solid(sum): - sum_sq = sum.copy() - sum_sq['sum_sq'] = sum['sum']**2 - return sum_sq - - - # After definining a solid, we are grouping them into a pipeline - pipeline = dagster.core.pipeline( - name='pandas_hello_world', - solids=[ - sum_solid, - sum_sq_solid, - ], - ) - -You might notice that there is no actual CSV file specified as inputs. This is because such parameters are passed in environment. This allows you to customize it in runtime. To run your solid, we'll pass that environment to the execution function. - -.. code-block:: python - - pipeline_result = dagster.execute_pipeline(pipeline, environment) - - -We can simplify the above example by using built-in dagster pandas inputs and outputs. - -.. code-block:: python - - # TODO updated example definition - -We can specify in order to get artifacts for the results.

In that case the environment is specified through yaml configuration files. - -The folder structure should be as follows. - -.. code-block - - pipeline_project_name/ - pipelines.yml - pipeline_module_1/ - env.yml - pipeline_module_2/ - env.yml - -Pipelines yml specify the pipelines that are present in current project.

In this case the transform is ``hello_world_transform_fn`` -and it is passed as parameter into the solid. It takes one or more -inputs and produces an output. All other concepts in a solid are the -metadata and structure that surround this core computation - -Inputs ---------- - -For each argument to the transform function, there is one -``InputDefinition`` object. It has a name, which must match the -parameters to the transform function. The input definitions define a -name, a dependency for the input (what upstream solid produces its -value, see below) and a number of sources. An input definition must -specify at least a dependency or a source. The input can have any number -of sources. - - -Output ---------- - -The ``OutputDefinition`` represents the output of the transform -function. - - - -Higher-level APIs ------------------- - -# TODO keep this section? - -Execution ---------- - -These are useless without being able to execute them. In order to -execute a solid, you need to package it up into a pipeline. - -.. code-block:: python - - pipeline = dagster.PipelineDefinition(name='hello_world', solids=[sum_solid]) - -Then you an execute it by providing an environment. You must provide -enough source data to create all the inputs necessary for the pipeline. - -.. code-block:: python - - environment = config.Environment( - sources={ - 'sum' : { - 'num_df' : config.Source(name='CSV', args={'path': 'path/to/input.csv'}) - } - } - ) - - pipeline_result = dagster.execute_pipeline( - dagster.ExecutionContext(), - pipeline, - environment - ) - - print(pipeline_result.result_for_solid('sum').transformed_value) - - -Dependencies ------------- - -So far we have demonstrated a single stage pipeline, which is obviously -of limited value. - -Imagine we wanted to add another stage which took the sum we produced -and squared that value. (Fancy!) - -.. code-block:: python - - # TODO example dependencies - -Note that input specifies that dependency. This means that the input -value passed to the transform can be generated by an upstream dependency -OR by an external source. This allows for the solid to be executable in -isolation or in the context of a pipeline. - -.. code-block:: python - - # TODO example driving - -The above executed both solids, even though one input was provided. The -input into sum\_sq\_solid was provided by the upstream result from the -output of sum\_solid. - -You can also execute subsets of the pipeline. Given the above pipeline, -you could specify that you only want to specify the first solid: - -.. code-block:: python - - # TODO example subdag execution - - - -Expectations ------------- - -Expectations are another reason to introduce logical seams between data -computations. They are a way to perform data quality tests or -statistical process control on data pipelines. +Go to https://dagster.readthedocs.io/en/latest/ for documentation! \ No newline at end of file From 89d1c856c19cf30b5b51b709d02ac59e6fa60506 Mon Sep 17 00:00:00 2001 From: Nicholas Schrock Date: Mon, 17 Sep 2018 07:36:32 -0700 Subject: [PATCH 100/103] Version bump --- python_modules/dagit/setup.py | 4 ++-- python_modules/dagster-ge/setup.py | 2 +- python_modules/dagster/dagster/sqlalchemy/common.py | 2 -- python_modules/dagster/dagster/version.py | 2 +- 4 files changed, 4 insertions(+), 6 deletions(-) diff --git a/python_modules/dagit/setup.py b/python_modules/dagit/setup.py index 81a9f7cd9f191..1d84796dc2348 100644 --- a/python_modules/dagit/setup.py +++ b/python_modules/dagit/setup.py @@ -18,7 +18,7 @@ def long_description(): version = {} with open("dagit/version.py") as fp: -
