The following summarizes Pinot's releases, from the latest one to the earliest one.
Before upgrading from one version to another one, read the release notes. While the Pinot committers strive to keep releases backward-compatible and introduce new features in a compatible manner, your environment may have a unique combination of configurations/data/schema that may have been somehow overlooked. Before you roll out a new release of Pinot on your cluster, it is best that you run the compatibility test suite that Pinot provides. The tests can be easily customized to suit the configurations and tables in your pinot cluster(s). As a good practice, you should build your own test suite, mirroring the table configurations, schema, sample data, and queries that are used in your cluster.

We are in the process of separating Helix and Pinot controllers, so that administrators can have the option of running independent Helix controllers and Pinot controllers.
We are in the process of moving towards supporting SQL query format and results.
We are in the process of separating instance and segment assignment using instance pools to optimize the number of Helix state transitions in Pinot clusters with thousands of tables.
Task management does not work correctly in this release, due to bugs in Helix. We will upgrade to Helix 0.9.2 (or later) version to get this fixed.
You must upgrade to this release before moving onto newer versions of Pinot release. The protocol between Pinot-broker and Pinot-server has been changed and this release has the code to retain compatibility moving forward. Skipping this release may (depending on your environment) cause query errors if brokers are upgraded and servers are in the process of being upgraded.
As always, we recommend that you upgrade controllers first, and then brokers and lastly the servers in order to have zero downtime in production clusters.
RetentionManager and OfflineSegmentIntervalChecker initial delays configurable (see PR )
Config to control kafka fetcher size and increase default (see PR )
Added a percent threshold to consider startup of services (see PR )
Make SingleConnectionBrokerRequestHandler as default (see PR )
Always enable default column feature, remove the configuration (see PR )
Remove redundant default broker configurations (see PR )
Removed some config keys in server(see PR )
Add config to disable HLC realtime segment (see PR )
Make RetentionManager and OfflineSegmentIntervalChecker initial delays configurable (see PR )
The following config variables are deprecated and will be removed in the next release:
pinot.broker.requestHandlerType will be removed, in favor of using the "singleConnection" broker request handler. If you have set this configuration, remove it and use the default type ("singleConnection") for broker request handler.
Pull Request introduces a backwards incompatible change to Pinot broker. If you use the Java constructor on HelixBrokerStarter class, then you will face a compilation error with this version. You will need to construct the object and call start() method in order to start the broker.
Pull Request introduces a backwards incompatible change for log4j configuration. If you used a custom log4j configuration (log4j.xml), you need to write a new log4j2 configuration (log4j2.xml). In addition, you may need to change the arguments on the command line to start Pinot components.
If you used Pinot-admin command to start Pinot components, you don't need any change. If you used your own commands to start pinot components, you will need to pass the new log4j2 config as a jvm parameter (i.e. substitute -Dlog4j.configuration or -Dlog4j.configurationFile argument with -Dlog4j2.configurationFile=log4j2.xml).
This release includes many new features on Pinot ingestion and connectors, query capability and a revamped controller UI.
This release includes many new features on Pinot ingestion and connectors (e.g., support for filtering during ingestion which is configurable in table config; support for json during ingestion; proto buf input format support and a new Pinot JDBC client), query capability (e.g., a new GROOVY transform function UDF) and admin functions (a revamped Cluster Manager UI & Query Console UI). It also contains many key bug fixes. See details below.
The release was cut from the following commit: d1b4586 and the following cherry-picks:
Allowing update on an existing instance config: PUT /instances/{instanceName} with Instance object as the pay-load ()

Support expression as the left-hand side for BETWEEN and IN clause (PR#5502)
Add a new field IngestionConfig in TableConfig — FilterConfig: ingestion level filtering of records, based on filter function. (PR#5597) — TransformConfig: ingestion level column transformations.

The release was cut from the following commit: 13c9ee9 and the following cherry-picks: 668b5e0, ee887b9
LinkedIn operates a large multi-tenant cluster that serves a business metrics dashboard, and noticed that their tables consisted of millions of small segments. This was leading to slow operations in Helix/Zookeeper, long running queries due to having too many tasks to process, as well as using more space because of a lack of compression.
To solve this problem they added the Segment Merge task, which compresses segments based on timestamps and rolls up/aggregates older data. The task can be run on a schedule or triggered manually via the Pinot REST API.
At the moment this feature is only available for offline tables, but will be added for real-time tables in a future release.
Major Changes:
Integrate enhanced SegmentProcessorFramework into MergeRollupTaskExecutor ()
Merge/Rollup task scheduler for offline tables. ()
Fix MergeRollupTask uploading segments not updating their metadata ()

Apache Pinot 0.11.0 has introduced many new features to extend the query abilities, e.g. the Multi-Stage query engine enables Pinot to do distributed joins, more sql syntax(DML support), query functions and indexes(Text index, Timestamp index) supported for new use cases. And as always, more integrations with other systems(E.g. Spark3, Flink).
This release introduced several awesome new features, including JSON index, lookup-based join support, geospatial support, TLS support for pinot connections, and various performance optimizations.

Helix Controller -> Pinot Controller -> Pinot Broker -> Pinot server
The new multi-stage query engine (a.k.a V2 query engine) is designed to support more complex SQL semantics such as JOIN, OVER window, MATCH_RECOGNIZE and eventually, make Pinot support closer to full ANSI SQL semantics. More to read: https://docs.pinot.apache.org/developers/advanced/v2-multi-stage-query-engine
Pinot operators can pause real-time consumption of events while queries are being executed, and then resume consumption when ready to do so again.\
More to read: https://medium.com/apache-pinot-developer-blog/pause-stream-consumption-on-apache-pinot-772a971ef403
The gapfilling functions allow users to interpolate data and perform powerful aggregations and data processing over time series data. More to read: https://www.startree.ai/blog/gapfill-function-for-time-series-datasets-in-pinot
Long waiting feature for segment generation on Spark 3.x.
Similar to the Spark Pinot connector, this allows Flink users to dump data from the Flink application to Pinot.
This feature allows better fine-grained control on pinot queries.
This allows users to have better query performance on the timestamp column for lower granularity. See: https://docs.pinot.apache.org/basics/indexing/timestamp-index
Wanna search text in real time? The new text indexing engine in Pinot supports the following capabilities:
New operator: LIKE
New operator: CONTAINS
Native text index, built from the ground up, focusing on Pinot’s time series use cases and utilizing existing Pinot indices and structures(inverted index, bitmap storage).
Real Time Text Index
Now you can use INSERT INTO [database.]table FROM FILE dataDirURI OPTION ( k=v ) [, OPTION (k=v)]* to load data into Pinot from a file using Minion. See: https://docs.pinot.apache.org/basics/data-import/from-query-console
This feature supports enabling deduplication for real-time tables, via a top-level table config. At a high level, primaryKey (as defined in the table schema) hashes are stored into in-memory data structures, and each incoming row is validated against it. Duplicate rows are dropped.
The expectation while using this feature is for the stream to be partitioned by the primary key, strictReplicaGroup routing to be enabled, and the configured stream consumer type to be low level. These requirements are therefore mandated via table config API's input validations.

Add TLS-support for client-pinot and pinot-internode connections () Upgrades to a TLS-enabled cluster can be performed safely and without downtime. To achieve a live-upgrade, go through the following steps:
First, configure alternate ingress ports for https/netty-tls on brokers, controllers, and servers. Restart the components with a rolling strategy to avoid cluster downtime.
Second, verify manually that https access to controllers and brokers is live. Then, configure all components to prefer TLS-enabled connections (while still allowing unsecured access). Restart the individual components.

Support added to extend upserts and allow deleting records from a realtime table. The design details can be found .
Preload segments with upsert snapshots to speedup table loading ()
Adds a feature to preload segments from a table that uses the upsert snapshot feature. The segments with validDocIds snapshots can be preloaded in a more efficient manner to speed up the table loading (thus server restarts).
TTL configs for upsert primary keys ()
Adds support for specifying expiry TTL for upsert primary key metadata cleanup.
Segment compaction for upsert real-time tables ()
Adds a new minion task to compact segments belonging to a real-time table with upserts.
Added spark3 support for Pinot Spark Connector ()
Also added support to pass pinot query options to spark connector ()
Adds new implementations of PinotDataBuffer that uses Unsafe java APIs and foreign memory APIs. Also added support for PinotDataBufferFactory to allow plugging in custom PinotDataBuffer implementations.

This feature allows better management of broker resources.
Drop results support ()
Adds a parameter to queryOptions to drop the resultTable from the response. This mode can be used to troubleshoot a query (which may have sensitive data in the result) using metadata only.
Make column order deterministic in segment ()
In segment metadata and index map, store columns in alphabetical order so that the result is deterministic. Segments generated before/after this PR will have different CRC, so during the upgrade, we might get segments with different CRC from old and new consuming servers. For the segment consumed during the upgrade, some downloads might be needed.
Allow configuring helix timeouts for EV dropped in Instance manager ()
Adds options to configure helix timeouts
external.view.dropped.max.wait.ms`` - The duration of time in milliseconds to wait for the external view to be dropped. Default - 20 minutes. external.view.check.interval.ms`` - The period in milliseconds in which to ping ZK for latest EV state.

[Clean up] Remove getColumnName() from AggregationFunction interface ()
0.3.0 release of Apache Pinot introduces the concept of plugins that makes it easy to extend and integrate with other systems.
The reason behind the architectural change from the previous release (0.2.0) and this release (0.3.0), is the possibility of extending Apache Pinot. The 0.2.0 release was not flexible enough to support new storage types nor new stream types. Basically, inserting a new functionality required to change too much code. Thus, the Pinot team went through an extensive refactoring and improvement of the source code.
For instance, the picture below shows the module dependencies of the 0.2.X or previous releases. If we wanted to support a new storage type, we would have had to change several modules. Pretty bad, huh?
select * FROM foo where text_col LIKE 'a%'select * from foo where text_col CONTAINS 'bar'Third, disable insecure connections via configuration. You may also have to set controller.vip.protocol and controller.vip.port and update the configuration files of any ingestion jobs. Restart components a final time and verify that insecure ingress via http is not available anymore.

Pinot input format: How to read records from various data/file formats: e.g. Avro/CSV/JSON/ORC/Parquet/Thrift
Pinot filesystem: How to operate files on various filesystems: e.g. Azure Data Lake/Google Cloud Storage/S3/HDFS
Pinot stream ingestion: How to ingest data stream from various upstream systems, e.g. Kafka/Kinesis/Eventhub
Pinot batch ingestion: How to run Pinot batch ingestion jobs in various frameworks, like Standalone, Hadoop, Spark.
Built shaded jars for each individual plugin
Added support to dynamically load pinot plugins at server startup time
Now the architecture supports a plug-and-play fashion, where new tools can be supported with little and simple extensions, without affecting big chunks of code. Integrations with new streaming services and data formats can be developed in a much more simple and convenient way.

It’s a disruptive upgrade from version 0.1.0 to this because of the protocol changes between Pinot Broker and Pinot Server. Ensure that you upgrade to release 0.2.0 first, then upgrade to this version.
If you build your own startable or war without using scripts generated in Pinot-distribution module. For Java 8, an environment variable “plugins.dir” is required for Pinot to find out where to load all the Pinot plugin jars. For Java 11, plugins directory is required to be explicitly set into classpath. See pinot-admin.sh as an example.
As always, we recommend that you upgrade controllers first, and then brokers and lastly the servers in order to have zero downtime in production clusters.
Kafka 0.9 is no longer included in the release distribution.
Pull request introduces a backward incompatible API change for segments management.
Removed segment toggle APIs
Removed list all segments in cluster APIs
Pull request deprecated below task related APIs:

Release Notes for version 1.1.0
This release comes with several features, SQL /UI/Perf enhancements Bugfixes across areas ranging from Multistage Query Engine to Ingestion, Storage format, SQL support, etc.
Support RelDistribution-based trait Planning (, )
Adds support for RelDistribution optimization for more accurate leaf-stage direct exchange/shuffle. Also extends partition optimization beyond leaf stage to entire query plan.
Applies optimization based on distribution trait in the mailbox/worker assignment stage
Fixes previous direct exchange which was decided based on the table partition hint. Now direct exchange is decided via distribution trait: it will applied if-and-only-if the trait propagated matches the exchange requirement.
Leaf stage planning with multi-semi join support ()
Solves the limitation of pinotQuery that supports limited amount of PlanNodes.
Splits the ServerRequest planning into 2 stages
First plan as much as possible into PinotQuery
Support for ArrayAgg aggregation function ()
Usage: ArrayAgg(column, 'dataType' [, 'isDistinct'])
Float type column is treated as Double in the multistage engine, so FLOAT type is not supported.
Supports data BOOLEAN, INT, LONG
Canonicalize SqlKind.OTHERS and SqlKind.OTHER_FUNCTIONS and support
concat as || operator ()
Capability for constant filter in QueryContext, with support for server to handle it (
Bugfix for evaluation of chained literal functions ()
Fixes to sort copy rule ( and )
Fixes duplicate results for literal queries ()
Use server config pinot.server.consumption.rate.limit to enable this feature
Server rate limiter is disabled by default (default value 0)
Supported in MergeRollupTask and RealtimeToOfflineSegmentsTask minion tasks
Use taskConfig segmentMapperFileSizeThresholdInBytes to specify the threshold size
Security feature that makes the keystore/truststore swappable.
Auto-reloads keystore/truststore (without need for a restart) if they are local files
Adds support for deterministic and sticky routing for a query / table / broker. This setting would lead to same server / set of servers (for MultiStageReplicaGroupSelector) being used for all queries of a given table.
Query option (takes precedence over fixed routing setting at table / broker config level)
SET "useFixedReplica"=true;
Table config (takes precedence over fixed routing setting at broker config level)
Use tableConfig dimensionTableConfig.errorOnDuplicatePrimaryKey=true to enable this behavior
Disabled by default
Support to force-commit specific partitions of a realtime table.
Partitions can be specified to the forceCommit API as a comma separated list of partition names or consuming segment names
Support to give the broker initial tags on startup.
Automatically updates brokerResource when broker joins the cluster for the first time
Broker tags are provided as comma-separated values in pinot.broker.instance.tags
StreamNative (the cloud SAAS offering of Pulsar) uses OAuth2 to authenticate clients to their Pulsar clusters.
For more information, see how to
Can be configured by adding the following properties to streamConfigs:
Introduces a new table rebalance boolean config lowDiskMode.Default value is false.
Applicable for rebalance with downtime=false.
When enabled, segments will first be offloaded from servers, then added to servers after offload is done. It may increase the total time of the rebalance, but can be useful when servers are low on disk space, and we want to scale up the cluster and rebalance the table to more servers.
Supports Vector Index on float array/multi-value columnz
Add predicate and function to retrieve topK closest vector. Example query
The function VectorSimilarity will return a double value where the first parameter is the embedding column and the second parameter is the search term embedding literal.
Since VectorSimilarity is a predicate, once config the topK, this predicate will return topk rows per segment. Then if you are using this index with other predicate, you may not get expected number of rows since the records matching other predicate might not in the topk rows.
Adds an upsert config deletedKeysTTL which will remove deleted keys from in-memory hashmap and mark the validDocID as invalid after the deletedKeysTTL threshold period.
Disabled by default. Enabled only if a valid value for deletedKeysTTL is set
Introduces the capability to specify a custom Lucene analyzer used by text index for indexing and search on an individual column basis.
Sample usage
Default Behavior falls back to using the standardAnalyzer unless the luceneAnalyzerClass property is specified.
Murmur3 support with optional fields seed and variant for the hash in functionConfig field of columnPartitionMap.Default value for seed is 0.
Added support for 2 variants of Murmur3: x86_32
Adds new MV dictionary encoded forward index format that only stores the unique MV entries.
This new index format can significantly reduce the index size when the MV entries repeat a lot
The new index format can be enabled during index creation, derived column creation, and segment reload
Adds support for 2 possible ways to handle null:
Table mode - which already exists
Column mode, which means that each column specifies its own nullability in the FieldSpec
Adds a new upsert config outOfOrderRecordColumn
When set to a non-null value, we check whether an event is OOO or not and then accordingly update the corresponding column value to true / false.
This will help in tracking which event is out-of-order while using skipUpsert
Can be used to save space. For eg: when a functionColumnPairs has a output type of bytes, such as when you use distinctcountrawhll.
Sample config
Supports instance assignment based pre-configured instance assignment map.
The assignment will always respect the mirrored servers in the pre-configured map
More details
Adds dimension as a valid option to table "type" in the /tables controller API
This patch adds a new config for upsert: dropOutOfOrderRecord
If set to true, pinot doesn't persist out-of-order events in the segment.
This feature is useful to
New configs for the RebalanceChecker periodic task:
controller.rebalance.checker.frequencyPeriod: 5min by default ; -1 to disable
controller.rebalanceChecker.initialDelayInSeconds
UltraLogLog ()UltraLogLog aggregations for Count Distinct (distinctCountULL and distinctCountRawULL)
UltraLogLog creation via Transform Function
UltraLogLog merging in MergeRollup
Ingestion via transformation function
Extracting estimates via query aggregation functions
Segment rollup aggregation
Broadly there are two configs that will enable this feature:
maxServerResponseSizeBytes: Maximum serialized response size across all servers for a query. This value is equally divided across all servers processing the query.
maxQueryResponseSizeBytes: Maximum length of the serialized response per server for a query
This is helpful when user has the entire JSON handy
UI still keeps Form Way to add Schema along with JSON view
Use option maxValueLength in jsonIndexConfig to restrict length of values
A value of 0 (or when the key is omitted) means there is no restriction
Supports serializing and writing MV columns in VarByteChunkForwardIndexWriterV4
Supports V4 reader that can be used to read SV var length, MV fixed length and MV var length buffers encoded with V4 writer
FrequentStringsSketch and FrequentLonsSketch aggregation functions ()Approximation aggregation functions for estimating the frequencies of items a dataset in a memory efficient way. More details in library.
Table index api to get the aggregate index details of all segments for a table.
URL/tables/{tableName}/indexes
Response format
The lead controller rebalance delay is now configurable with controller.resource.rebalance.delay_ms
Changing rebalance configurations will now update the lead controller resource
Adds support for Pinot configuration through ENV variables with Dynamic mapping.
More details in issue:
Sample configs through ENV
HLL++ has higher accuracy than HLL when cardinality of dimension is at 10k-100k.
More details
Adds query rewriting logic to transform a "virtual" UDF, clpMatch, into a boolean expression on the columns of a CLP-encoded field.
To use the rewriter, modify broker config to add org.apache.pinot.sql.parsers.rewriter.ClpRewriter to pinot.broker.query.rewriter.class.names.

Bugfix to distribute Pinot as a multi-release JAR (, )
Fix a race condition for upsert compaction (). Notes on backward incompatibility below:
This PR is introducing backward incompatibility for UpsertCompactionTask. Previously, we allowed to configure the compaction task without the snapshot enabled. We found that using in-memory based validDocIds is a bit dangerous as it will not give us the consistency (e.g. fetching validDocIds bitmap while the server is restarting & updating validDocIds).
We now enforce the enableSnapshot=true for UpsertCompactionTask if the advanced customer wants to run the compaction with the in-memory validDocId bitmap.
update maven-jar-plugin and maven-enforcer-plugin version (#11637)
Update testng as the test provider explicitly instead of relying on the classpath. ()
Update compatibility verifier version ()
As a side effect, is_colocated_by_join_keysquery option is reintroduced to ensure dynamic broadcast which can also benefit from direct exchange optimization
Allows propagation of partition distribution trait info across the tree to be used during Physical Planning phase. It can be used in the following scenarios (will follow up in separate PRs)
Note on backward incompatbility
is_colocated_by_join_keys hint is now required for making colocated joins
it should only affect semi-join b/c it is the only one utilizing broadcast exchange but were pulled to act as direct exchange.
inner/left/right/full join should automatically apply colocation thus the backward incompatibility should not affect these.

x64_32variantfunctionConfigx86_32Examples of functionConfig;
Here there is no functionConfig configured, so the seed value will be 0 and variant will be x86_32.
Here the seed is configured as 9001 but as no variant is provided, x86_32 will be picked up.
Here the variant is mentioned so Murmur3 will use the x64_32 variant with 9001 as seed.
Note on users using Debezium and Murmur3 as partitioning function :
The partitioning key should be set up on either of byte[], String or long[] columns.
On pinot variant should be set as x64_32 and seed should be set as 9001.
FieldConfig:Or use the new index JSON:
The default value for enableColumnBasedNullHandling is false. When set to true, Pinot will ignore TableConfig.IndexingConfig.nullHandlingEnabled and columns will be nullable if and only if FieldSpec.notNull is false, which is also the default value.
Save disk-usage
Avoid any confusion when using skipUpsert for partial-upsert tables as nulls start showing up for columns where a previous non-null was encountered and we don't know if it's an out-of-order event or not.
New configs added for RebalanceConfig:
heartbeatIntervalInMs: 300_000 i.e. 5min
heartbeatTimeoutInMs: 3600_000 i.e. 1hr
maxAttempts: 3 by default, i.e. the original run plus two retries
retryInitialDelayInMs: 300_000 i.e. 5min, for exponential backoff w/ jitters
New metrics to monitor rebalance and its retries:
TABLE_REBALANCE_FAILURE("TableRebalanceFailure", false), emit from TableRebalancer.rebalanceTable()
TABLE_REBALANCE_EXECUTION_TIME_MS("tableRebalanceExecutionTimeMs", false), emit from TableRebalancer.rebalanceTable()
TABLE_REBALANCE_FAILURE_DETECTED("TableRebalanceFailureDetected", false), emit from RebalanceChecker
TABLE_REBALANCE_RETRY("TableRebalanceRetry", false), emit from RebalanceChecker
New restful API
DELETE /tables/{tableName}/rebalance API to stop rebalance. In comparison, POST /tables/{tableName}/rebalance was used to start one.
Support for UltraLogLog in Star-Tree indexes
