This release includes the several new features, enhancements, and bug fixes, including the following highlights:
Multi-stage query engine: , , and . Learn how to or more about how the works.
Support for
Initial (phase 1) Query runtime for window functions with ORDER BY within the OVER() clause (#10449)
Support for the ranking ROW_NUMBER() window function (, )
Set operations support:
Support SetOperations (UNION, INTERSECT, MINUS) compilation in query planner ()
Timestamp and Date Operations
Support TIMESTAMP type and date ops functions ()
Support more aggregation functions that are currently implementable ()
Support multi-value aggregation functions ()
Support Sketch based functions (), ()
Make Intermediate Stage Worker Assignment Tenant Aware ()
Evaluate literal expressions during query parsing, enabling more efficient query execution (
Added support for partition parallelism in partitioned table scans, allowing for more efficient data retrieval ()
[multistage]Adding more tuple sketch scalar functions and integration tests ()
Enhanced the multi-stage group-by executor to support limiting the number of groups,
NULL support for ORDER BY, DISTINCT, GROUP BY, value transform functions and filtering.
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).
Adds support for specifying expiry TTL for upsert primary key metadata cleanup.
Adds a new minion task to compact segments belonging to a real-time table with upserts.
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.
Allows overriding index configs at tier level, allowing for more flexible index configurations for different tiers.
Rebalance
Added new configuration options below which allow use of a bounded thread pool and allocate capacities for it.
This feature allows better management of broker resources.
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.
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.
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.
This PR makes Pinot case insensitive be default, and removes the deprecated property enable.case.insensitive.pql
