• [dagster-ui] Asset materializations can now be reported from the dropdown menu in the asset list view.
• [dagster-dbt] DbtProject is adopted and no longer experimental. Using DbtProject helps achieve a setup where the dbt manifest file and dbt dependencies are available and up-to-date, during development and in production. Check out the API docs for more: https://docs.dagster.io/_apidocs/libraries/dagster-dbt#dagster_dbt.DbtProject.
• [dagster-dbt] The —use-dbt-project flag was introduced for the cli command dagster-dbt project scaffold. Creating a Dagster project wrapping a dbt project using that flag will include a DbtProject .
• [dagster-ui] The Dagster UI now loads events in batches of 1000 in the run log viewer, instead of batches of 10000. This value can be adjusted by setting the DAGSTER_UI_EVENT_LOAD_CHUNK_SIZE environment variable on the Dagster webserver.
• Asset backfills will now retry if there is an unexpected exception raised in the middle of the backfill. Previously, they would only retry if there was a problem connecting to the code server while launching runs in the backfill.
• Added the ability to monitor jobs which have failed to start in time with the RunFailureReason.START_TIMEOUT run monitoring failure reason. Thanks @jobicarter!
• [experimental] Introduced the ability to attach code references to your assets, which allow you to view source code for an asset in your editor or in git source control. For more information, see the code references docs: https://docs.dagster.io/guides/dagster/code-references.
• [ui] Performance improvements to loading the asset overview tab.
• [ui] Performance improvements for rendering run gantt charts with 1000’s of ops/steps.

• For subselections of graph-backed multi-assets, there are some situations where we used to unnecessarily execute some of the non-selected assets. Now, we no longer execute them in those situations. There are also some situations where we would skip execution of some ops that might be needed. More information on the particulars is available here.
• Fixed the @graph_asset decorator overload missing an owners argument, thanks @askvinni!
• Fixed behavior of passing custom image config to the K8sRunLauncher, thanks @marchinho11!

• [dagster-aws] Fixed an issue where the EMR step launcher would sometimes fail due to multiple versions of the dateutil package being installed in the default EMR python evnrionment.
• [ui] The “Create date” column in the runs table now correctly shows the time at which a run was created instead of the time when it started to execute.
• [ui] Fixed dark mode colors in run partitions graphs.
• [auto-materialize] Fixed an issue which could cause errors in the AutoMaterializeRule.skip_on_parent_missing rule when a parent asset had its PartitionsDefinition changed.
• [declarative-automation] Fixed an issue which could cause errors when viewing the evaluation history of assets with AutomationConditions.
• [declarative-automation] Previously, AutomationCondition.newly_updated() would trigger on any ASSET_OBSERVATION event. Now, it only triggers when the data version on that event changes.

Breaking Changes

• [dagster-dbt] The cli command dagster-dbt project prepare-for-deployment has been replaced by dagster-dbt project prepare-and-package.
• [dagster-dbt] During development,DbtProject no longer prepares the dbt manifest file and dbt dependencies in its constructor during initialization. This process has been moved to prepare_if_dev(), that can be called on the DbtProject instance after initialization. Check out the API docs for more: https://docs.dagster.io/_apidocs/libraries/dagster-dbt#dagster_dbt.DbtProject.prepare_if_dev.

Deprecations

1.7.9 (core) / 0.23.9 (libraries)

New

• Dagster will now display a “storage kind” tag on assets in the UI, similar to the existing compute kind. To set storage kind for an asset, set its dagster/storage_kind tag.
• You can now set retry policy on dbt assets, to enable coarse-grained retries with delay and jitter. For fine-grained partial retries, we still recommend invoking dbt retry within a try/except block to avoid unnecessary, duplicate work.
• AssetExecutionContext now exposes a has_partition_key_range property.
• The owners, metadata, tags, and deps properties on AssetSpec are no longer Optional. The AssetSpec constructor still accepts None values, which are coerced to empty collections of the relevant type.
• The docker_executor and k8s_job_executor now consider at most 1000 events at a time when loading events from the current run to determine which steps should be launched. This value can be tuned by setting the DAGSTER_EXECUTOR_POP_EVENTS_LIMIT environment variable in the run process.
• Added a dagster/retry_on_asset_or_op_failure tag that can be added to jobs to override run retry behavior for runs of specific jobs. See the docs for more information.

• A new “Runs” tab on the backfill details page allows you to see list and timeline views of the runs launched by the backfill.
• [dagster-dbt] dbt will now attach relation identifier metadata to asset materializations to indicate where the built model is materialized to.
• [dagster-graphql] The GraphQL Python client will now include the HTTP error code in the exception when a query fails. Thanks @yuvalgimmunai!

Bugfixes

• Fixed sensor logging behavior with the @multi_asset_sensor.
• ScheduleDefinition now properly supports being passed a RunConfig object.
• When an asset function returns a MaterializeResult, but the function has no type annotation, previously, the IO manager would still be invoked with a None value. Now, the IO manager is not invoked.
• The AssetSpec constructor now raises an error if an invalid owner string is passed to it.
• When using the graph_multi_asset decorator, the code_version property on AssetOuts passed in used to be ignored. Now, they no longer are.
• [dagster-deltalake] Fixed GcsConfig import error and type error for partitioned assets (Thanks @thmswt)
• The asset graph and asset catalog now show the materialization status of External assets (when manually reported) rather than showing “Never observed”

• Typing a % into the asset graph’s query selector no longer crashes the UI.
• “Materializing” states on the asset graph animate properly in both light and dark themes.
• Thanks to @lautaro79 for fixing a helm chart issue.

Breaking Changes

• Subclasses of MetadataValue have been changed from NamedTuples to Pydantic models. NamedTuple functionality on these classes was not part of Dagster’s stable public API, but usages relying on their tuple-ness may break. For example: calling json.dumps on collections that include them.

Deprecations

• [dagster-dbt] Support for dbt-core==1.5.* has been removed, as it has reached end of life in April 2024.
