It organizes data in a hierarchical structure, allowing for flexible management and retrieval capabilities.\nBefore you start using Pizza, familiarize yourself with the following key concepts:\n [Pizza Concepts] Concepts #  Cluster #  A cluster represents a set of interconnected nodes that collectively form the Pizza search engine. Nodes within a cluster collaborate to store and process data efficiently. Clusters can span multiple physical locations for fault tolerance and scalability.\nZone #  A zone is a logical grouping of nodes within a cluster. Zones are typically organized based on geographic proximity or network topology. They facilitate data replication and fault tolerance strategies by ensuring redundancy across different zones.\nRegion #  A region is a further subdivision within a zone, typically representing a smaller geographical area or a distinct network segment. Regions help optimize data access and reduce latency by distributing data closer to users or applications.\nNamespace #  Pizza support multi-tenant by design. A namespace is a logical container for collections of related data. It serves as a namespace for collections, providing isolation and organization. Namespaces can be used to group data according to different criteria such as application domain, user, or data type.\nCollection #  A collection is a grouping of documents with similar characteristics or attributes. Collections represent the primary unit of storage and retrieval within Pizza. Each collection is vertically partitioned into \u0026ldquo;rollings\u0026rdquo; to efficiently manage large datasets.\nRolling #  A rolling is a vertical partition of the entire collection dataset. Each rolling contains a subset of documents, with a maximum limit of 4.2 billion documents per rolling. Documents within a rolling are assigned an auto-increment sequence document ID, which is a uint32. Once a rolling is filled, the next rolling is automatically assigned, ensuring infinite scalability.\nPartition #  A partition is a logical split and separation of data within a single rolling. Fixed at 256 partitions per rolling, partitions enable horizontal scalability and performance optimization by distributing data across multiple shards. Partitions are dynamically mapped to shards and can be scaled out or merged for better search performance.\nShard #  A shard is a physical container for partitions within a single rolling of a collection. Each rolling can have a different setup of shards, allowing for customized scalability and performance optimization. Shards contain partitions within a single rolling, enabling efficient data distribution and retrieval.\nDocument #  A document represents a unit of data indexed by the Pizza search engine. Documents can be of various types, such as text, images, or structured data. Each document contains fields that store specific attributes or properties, making it searchable and retrievable.\nField #  A field is a specific attribute or property of a document. Fields contain the actual data that is indexed and searched within documents. Examples of fields include title, content, author, date, etc.\nStore #  In Pizza, the \u0026ldquo;Store\u0026rdquo; refers to the primary storage for documents, also known as forward records. By default, it utilizes Parquet for storage, with the option to integrate other external storage types in the future.\nIndex #  An index is a data structure used to efficiently retrieve documents based on search queries. It maps terms or keywords to the documents containing those terms, enabling fast lookup and retrieval. Indices are built and maintained based on the fields within documents.\nRelationships #  Cluster to Zone/Region #  A cluster consists of one or more zones, which may further contain multiple regions. Zones and regions facilitate data replication and fault tolerance strategies within the cluster.\nNamespace to Collection #  Namespaces contain one or more collections, providing a logical grouping for related data. Collections within the same namespace share common management and access policies.\nCollection to Rolling #  As data within a Collection grows, it\u0026rsquo;s vertically partitioned into Rollings to manage large datasets efficiently. Rollings represent vertical partitions of a Collection\u0026rsquo;s dataset, allowing dynamic scaling and efficient querying of subsets of data.\nRolling to Partition #  Single Rolling are horizontally partitioned into 256 partitions, each containing a subset of documents. Partitions enable horizontal scalability and performance optimization within a rolling.\nPartition to Shard #  Partitions are dynamically mapped to shards within a collection. Shards can scale out to multiple shards or merge back into a single shard for improved search performance and resource utilization.\nDocument to Field #  Documents consist of fields that store specific attributes or properties. Fields enable structured indexing and searching of documents based on their content.\nStore to Index #  The store persists documents and associated metadata, while indices facilitate efficient retrieval of documents based on search queries. Stores and indices work together to provide fast and reliable data access within the Pizza search engine.\n"});index.add({'id':3,'href':'/docs/references/collection/create/','title':"Create a collection",'section':"Collection",'content':"Create a collection #  Creates a new collection.\nExamples #  The following request creates a new collection called my-collection in the namespace my-namespace:\nPUT /my-namespace:my-collection If creating a collection within the default namespace, it can be simplified as:\nPUT /my-collection Request #  PUT /[\u0026lt;namespace\u0026gt;:]\u0026lt;name\u0026gt; Path parameters #   \u0026lt;namespace\u0026gt;\n(Optional, string) The namespace which the collection belongs to.

You can specify calendar intervals using the unit name, such as month, or as a single unit quantity, such as 1M. For example, day and 1d are equivalent. Multiple quantities, such as 2d, are not supported.\nThe accepted calendar intervals are:\n minute, 1m\nAll minutes begin at 00 seconds. One minute is the interval between 00 seconds of the first minute and 00 seconds of the following minute in the specified time zone, compensating for any intervening leap seconds, so that the number of minutes and seconds past the hour is the same at the start and end. hour, 1h\nAll hours begin at 00 minutes and 00 seconds. One hour (1h) is the interval between 00:00 minutes of the first hour and 00:00 minutes of the following hour in the specified time zone, compensating for any intervening leap seconds, so that the number of minutes and seconds past the hour is the same at the start and end. day, 1d\nAll days begin at the earliest possible time, which is usually 00:00:00 (midnight). One day (1d) is the interval between the start of the day and the start of the following day in the specified time zone, compensating for any intervening time changes. week, 1w\nOne week is the interval between the start day_of_week:hour:minute:second and the same day of the week and time of the following week in the specified time zone. month, 1M\nOne month is the interval between the start day of the month and time of day and the same day of the month and time of the following month in the specified time zone, so that the day of the month and time of day are the same at the start and end. quarter, 1q\nOne quarter is the interval between the start day of the month and time of day and the same day of the month and time of day three months later, so that the day of the month and time of day are the same at the start and end. year, 1y\nOne year is the interval between the start day of the month and time of day and the same day of the month and time of day the following year in the specified time zone, so that the date and time are the same at the start and end.  fixed_interval #  Fixed intervals are configured with the fixed_interval parameter.\nIn contrast to calendar-aware intervals, fixed intervals are a fixed number of SI units and never deviate, regardless of where they fall on the calendar. One second is always composed of 1000ms. This allows fixed intervals to be specified in any multiple of the supported units.\nHowever, it means fixed intervals cannot express other units such as months, since the duration of a month is not a fixed quantity. Attempting to specify a calendar interval like month or quarter will throw an exception.\nThe accepted units for fixed intervals are:\n milliseconds (ms)\nA single millisecond. This is a very, very small interval. seconds (s)\nDefined as 1000 milliseconds each. minutes (m)\nDefined as 60 seconds each (60,000 milliseconds). All minutes begin at 00 seconds. hours (h)\nDefined as 60 minutes each (3,600,000 milliseconds). All hours begin at 00 minutes and 00 seconds. days (d)\nDefined as 24 hours (86,400,000 milliseconds).

High scalability, supports very large-scale clusters, beyond petabytes. Native integration with LLMs and ML, empowering AI-Native enterprise innovation. Design with storage and computation separation, and also storage and index separation.  Architecture #  Pizza employs a share-nothing architecture, designed for modern hardware, ensuring complete isolation of resources at both the node and per-CPU level. Pizza embraces a fully asynchronous manner to access I/O and network resources, unleash the power of multiple cores, large memory and NVME SSD.\n Learn more about Pizza\u0026rsquo;s architecture.\nWhy Pizza #  The name Pizza was taken from our unique sharding design.\nThe documents in Pizza are persisted as Parquet files in object storage. Native integration with other big data systems through object storage and the standard Parquet format.\nWhen to use Pizza #  Pizza is good fit when:\n You have latency-sensitive search applications that millisecond matters. You need fresh data, your data is mutable, and you need fast queries. You need to handle high concurrency with complex queries. You need to handle more than petabytes data for user-facing use cases. You need to handle JOIN for complex data relations. You need to keep thousands of fields, but only a handful are subject to change. You need to manage both structured and unstructured data in a cohesive manner.  Pizza is designed to address these problems at heart, to solve real critical business issues, serve your data-driven applications in realtime at very large scale. Enhance and enrich the data experiences of your end-users.\nDesign choices #  The philosophy of Pizza is that indices should be designed per use case, and should not attempt to fit every use case with a single index. Therefore, we introduced Views, which allow combining different document sources into a single index or separating a document into different layers of indices for different use cases.\nBy emphasizes the decoupling of storage and computation, as well as the separation of storage and index. Which enables efficient and scalable data processing by allowing independent management and optimization of storage resources, computational resources, and indexing strategies.\nNative integration with LLMs (Language Models) and ML (Machine Learning) technologies is a key aspect of Pizza, providing powerful capabilities for AI-Native enterprise innovation. By seamlessly integrating with LLMs and ML frameworks, Pizza enables advanced natural language processing, machine learning, and data analytics directly within the search and data retrieval pipeline.\nWe are in the process of building the next-generation search infrastructure, driven by our unwavering commitment to delivering real-time search experiences for enterprises, unlocking the potential of modern hardware, and catering to the demands of high concurrency and high throughput in the most challenging of environments.\nNext step #   Install and configure Pizza.\n"});index.add({'id':14,'href':'/docs/references/aggregation/percentiles/','title':"Percentiles aggregation",'section':"Aggregation",'content':"Percentiles aggregation #  A multi-value metrics aggregation that calculates one or more percentiles over numeric values extracted from the aggregated documents.\nPercentiles show the point at which a certain percentage of observed values occur.

The response will look like this:\n{ ... \u0026#34;aggregations\u0026#34;: { \u0026#34;load_time_outlier\u0026#34;: { \u0026#34;values\u0026#34;: { \u0026#34;1.0\u0026#34;: 10.0, \u0026#34;5.0\u0026#34;: 30.0, \u0026#34;25.0\u0026#34;: 170.0, \u0026#34;50.0\u0026#34;: 445.0, \u0026#34;75.0\u0026#34;: 720.0, \u0026#34;95.0\u0026#34;: 940.0, \u0026#34;99.0\u0026#34;: 980.0 } } } } As you can see, the aggregation will return a calculated value for each percentile in the default range. If we assume response times are in milliseconds, it is immediately obvious that the webpage normally loads in 10-725ms, but occasionally spikes to 945-985ms.\nOften, administrators are only interested in outliers — the extreme percentiles. We can specify just the percents we are interested in (requested percentiles must be a value between 0-100 inclusive):\nPOST latency/_search { \u0026#34;aggs\u0026#34;: { \u0026#34;load_time_outlier\u0026#34;: { \u0026#34;percentiles\u0026#34;: { \u0026#34;field\u0026#34;: \u0026#34;load_time\u0026#34;, \u0026#34;percents\u0026#34;: [95, 99, 99.9] } } } } Parameters for avg #   field\n(Required, string) Field you wish to aggregate. percents\n(Optional, array) A range of percentiles that are calculated.

Each CPU core and associated threads operate independently, without sharing memory or resources with other cores or nodes. Additionally, Pizza embraces a fully asynchronous manner to access I/O and network resources, leveraging technologies like io_uring for efficient I/O operations.\n [Pizza Architecture] Why Share-Nothing and Asynchronous I/O? #  The combination of share-nothing architecture and asynchronous I/O enables Pizza to seamlessly scale across large-scale datasets and high-throughput workloads, along with optimal performance and high resource utilization.\nMulti-Core Trending and Hardware Considerations #  As hardware trends towards increasing numbers of cores per machine, share-nothing architectures become increasingly relevant and advantageous. With machines featuring thousands of cores becoming more common, share-nothing architectures enable efficient utilization of parallelism without encountering bottlenecks associated with shared resources.\nContention and Locking Issues #  In share-everything architectures, contention for shared resources and locking mechanisms can become significant bottlenecks, especially in highly parallel environments. Share-nothing architectures eliminate these contention points by ensuring each node operates independently, avoiding the need for centralized locking mechanisms and reducing contention-related performance degradation.\nFault Isolation and Resilience #  Pizza\u0026rsquo;s share-nothing architecture enhances fault isolation and system resilience. Each CPU core and thread operates autonomously, minimizing the impact of failures or performance degradation on other cores or nodes. Similarly, asynchronous I/O operations isolate I/O-related failures, ensuring that failures in one operation do not affect the execution of others.\nNUMA and Cache-Friendly Design #  Pizza is designed to be NUMA-friendly and local cache or memory access-friendly. By minimizing memory access latency and optimizing performance on NUMA architectures, Pizza ensures efficient memory access and optimal performance. Additionally, its cache-friendly design eliminates the need to access remote memory in other CPU\u0026rsquo;s address spaces, reducing cache coherency overhead and improving overall performance.\nAsynchronous I/O #  Pizza employs asynchronous I/O and io_uring for efficient, non-blocking I/O operations, enhancing performance and scalability. Unlike traditional synchronous I/O, which involves blocking system calls, asynchronous I/O enables Pizza to reduce latency and improve resource utilization, especially in I/O-bound scenarios. With io_uring, a high-performance asynchronous I/O framework in the Linux kernel, Pizza minimizes system call overhead and optimizes buffer management. This approach delivers improved performance, scalability, resource efficiency, and a better user experience.\n"});index.add({'id':41,'href':'/docs/references/','title':"References",'section':"Documentation",'content':"References #  Data management #    Namespace APIs  Collection APIs  Document APIs  Index APIs  Search and analyze #    Search you data  Aggregations  "});index.add({'id':42,'href':'/docs/administration/','title':"Administration",'section':"Documentation",'content':"Administration #  Cluster management #  Search and analyze #  "});index.add({'id':43,'href':'/docs/overview/sharding/','title':"Why named Pizza",'section':"Overview",'content':"Why named Pizza? #  Do you wonder why this project is named Pizza?\nTo infinity scaling #  Pizza solves the challenge of managing massive data seamlessly. Imagine creating a collection and continuously adding documents, from zero to petabytes, without the need to worry about sharding or reindexing. Scaling your machine becomes effortless, ensuring a smooth, seamless, and painless experience for application developers.\nSharding puzzle #  One of the world\u0026rsquo;s three major challenges: What is the appropriate size for an index shard?\n [Sharding Puzzle!] Shards are like cars that transport your data, but determining how many shards you need is challenging because the amount of data is unpredictable and could continuously grow.\n [Sizing Puzzle!] Traditional sharding methods have several shortcomings. Currently, distributed system storage partitioning methods mainly include:\n Range-based partitioning methods require data to have a high dispersion in value ranges. Fixed-factor hash partitioning methods, set at database creation, may lead to over-allocation of resources if the partition factor is too large or performance issues if it\u0026rsquo;s too small. Consistent hashing algorithms lack adaptability to heterogeneous systems and flexibility in data partitioning, resulting in complex operations and suboptimal resource utilization.  Is there any other approach?\nPizza\u0026rsquo;s design #  Pizza does things differently!\nStart with document ID #  Pizza facilitates updates, and it\u0026rsquo;s top-notch. Ensuring efficient updates requires a unique identity for each document. While accommodating a vast dataset beyond trillions of documents, one can opt for a string-based UUID or utilize a uint64 or uint128 assigned to each document. However, utilizing a wide-sized primary key may lead to resource wastage, unnecessary compression, or conversion.\nIn Pizza, document identification follows a two-dimensional approach. Each document is assigned a unique identity comprising the rolling ID (rolling_id) and the internal asigned ID (seq_doc_id) within this rolling. These IDs are structured for efficiency, incorporating partition positions for rapid data localization. Rolling IDs and assigned document IDs increment automatically. Document value ranges vary based on numeric types chosen, accommodating trillions of documents. User-defined IDs seamlessly map to unique IDs.\nWith this design:\n Assigned ID format: [rolling_id], [seq_doc_id]. Assigned IDs adopt a composite two-dimensional structure. Assigned IDs are compact numeric types designed to support massive datasets. Assigned IDs are self-descriptive, include partition positions as routing for rapid data access. Rolling ID serves as metadata-level description and does not require persistence with each record. The space allocated for sequence assigned IDs is quite compact and compression friendly. Assigned ID becomes globally identity is also good fit to support frequently updates.  Within a single collection, Pizza offers varying document value ranges to accommodate different scale requirements, For [UInt8, UInt32] the capability estimated as rolling_id ranges from 0 to 255 for UInt8 types and seq_doc_id range from 0 to 4,294,967,295 for UInt32 types. Which can sustain [0 : 1,095,216,660,225] documents. if we scale rolling_id to use UInt16, then it will be [0 : 65,535], [0 : 4,294,967,295] = [0 : 281,470,681,677,825], which means 281 trillions scale, should be good start for any case.\nThese capabilities enable Pizza to handle collections of varying sizes, from smaller-scale to trillions of documents, efficiently and smoothly scale on demand.\nUser-defined IDs #  \u0026ldquo;But my IDs was shipped from external database\u0026rdquo;\nThat\u0026rsquo;s fair, Pizza handle this simply do map the UUID to an unique assigned document ID.\nFor example with this document creation:\nPOST /my-collection/_doc/myid { \u0026#34;message\u0026#34;: \u0026#34;GET /search HTTP/1.1 200 1070000\u0026#34;, \u0026#34;org\u0026#34;: { \u0026#34;id\u0026#34;: \u0026#34;infini\u0026#34; } } You will get:\n{ \u0026#34;_key\u0026#34;: \u0026#34;myid\u0026#34;, \u0026#34;_id\u0026#34;: \u0026#34;0,123\u0026#34;, \u0026#34;_version\u0026#34;: 1, \u0026#34;_namespace\u0026#34;: \u0026#34;default\u0026#34;, \u0026#34;_collection\u0026#34;: \u0026#34;my-collection\u0026#34;, \u0026#34;result\u0026#34;: \u0026#34;created\u0026#34;, ... } The _id valued 0,123 means a unique Pizza document ID was assigned to myid within this collection.\nInstead of passing the UUID throughout the further process, it\u0026rsquo;s common to begin with a search, and you will get a search result. The document in the search result should contain both _id and _key. pass both of them as the document identity should work.\nJust like a Pizza #  As you\u0026rsquo;ve noted, the maximum number of documents in a single rolling is a fixed size of 4,294,967,295, typically suitable for smaller use cases. The fixed capacity of single rolling is not a bug, it is a feature!\nThink of the rolling as the iron plate used for cooking the Pizza, and sending data to the rolling is akin to adding your delicious ingredients to that iron plate.\nWe ingest the data, we enjoy the pizza, just like that!\n [Yummy Pizza!] More Pizza - Rolling #  So you have number of documents beyond 4,294,967,295?\nNo worries, Let\u0026rsquo;s roll to another rolling, more rolling, more pizza, the party won\u0026rsquo;t stop tonight.\n [More Pizza!] When the capacity of a rolling is exceeded, data is automatically switched to the next rolling for continued writing.\nRollings can grow infinitely to meet ongoing growth requirements.\nPackaged Pizza #  There are many benefits fo package data like Pizza:\n Each rolling has a fixed size for ease of distribution and physical resource management. The number and size of shards are predictable. Shards are generated on demand, eliminating the need for advance planning. Scalability is infinite, allowing for horizontal expansion. Stable and predictable read/write performance.   [Packaged Pizza!] Slicing with partition #  Wait, 4.2 billion is not a small number, it may choke anyway, so we introduce partitions within rolling, just like we share slices of pizza to friends.\n [Slicing Pizza!] A single rolling can be split into a maximum of 256 physical partitions by default (configurable at creation). A lookup table is used to maintain the relationship between logical partitions and physical shards.\n [Slicing Pizza!] Physical shards and logical partitions can be dynamically split or merged. In scenarios with low write pressure, all partition data within a single shard is consolidated, appearing as a single data directory physically.\nHash based routing #  How about if we have more than one rolling, how do I know which rolling contains these UUID?\nCustom or assigned IDs are hashed based to establish a one-to-one relationship with partitions:\n[HASH(KEY) or ID] % 256 = PARTITION_ID\n [Routing Slices!] The worst case is the request need to revisit same partition across all rollings, but the scope is limited as stepped with 4.2b, also we can have UUID mapping cache ahead.\nAlways better to use Pizza assigned _id rather the _key for mutation, as _rolling_id is part of _id, so Pizza know which _rolling need to talk without ask.\nUltimate scaling #  Lastly, we will talk about replica, each shard can have replicas, to scale out for more search throughput.\n [Sharding Architecture] Rolling, Partition, Replica - three dimensions for ultimate scaling.\nThe more data you feed in, the more pizza you cook. Enjoy your yummy data!\n"});index.add({'id':44,'href':'/docs/overview/realtime/','title':"How realtime works",'section':"Overview",'content':"How realtime works? #  Do you like to let your customer wait? #   [Pizza in Realtime] "});index.add({'id':45,'href':'/docs/release-notes/','title':"Release notes",'section':"Documentation",'content':"Release notes #  Information about release notes of INFINI Pizza is provided here.\n0.1.0 #  Breaking changes #  Features #  Bug fix #  Improvements #  "});index.add({'id':46,'href':'/docs/references/document/fetch/','title':"Fetch a document",'section':"Document",'content':"Fetch a document #  Retrieve an existing document by specifying its unique identifier.\nExamples #  Fetch a document from the my-collection collection with customized uuid news_001:\nGET /my-collection/_doc/news_001 The API returns the following result:\n{ \u0026#34;_id\u0026#34;: \u0026#34;0,0\u0026#34;, \u0026#34;_version\u0026#34;: 1, \u0026#34;_namespace\u0026#34;: \u0026#34;default\u0026#34;, \u0026#34;_collection\u0026#34;: \u0026#34;my-collection\u0026#34;, \u0026#34;_key\u0026#34; : \u0026#34;news_001\u0026#34;, \u0026#34;found\u0026#34;: true, \u0026#34;_source\u0026#34; : { \u0026#34;message\u0026#34;: \u0026#34;GET /search HTTP/1.1 200 1070000\u0026#34;, \u0026#34;org\u0026#34;: { \u0026#34;id\u0026#34;: \u0026#34;infini\u0026#34; } } } As you can see, the customized uuid are represented as _key within the document, and there is also a _id returned with value 0,0, this is the internal id generated by Pizza, and it is guaranteed to be unique, so you can also fetch this document by this value like this:\nGET /my-collection/_doc/0,0 Request #  POST /\u0026lt;target\u0026gt;/_doc/\u0026lt;doc_id\u0026gt; Path parameters #   \u0026lt;target\u0026gt;\n(Required, string) Name of the collection to target. \u0026lt;doc_id\u0026gt;\n(Required, string) The unique identify of this document, support both _key or _id.
