Description This PR adds Ingestion Aggregation. The design doc can be found https://github.com/apache/pinot/issues/8360. This feature aggregates values at ingestion time, which reduces the number of rows stores (thus speeding up queries), using the same strategy as the 'aggregateMetrics' feature. This expands the feature to include, COUNT, MIN, and MAX, with the ability to expand further. Upgrade Notes Does this PR prevent a zero down-time upgrade? (Assume upgrade order: Controller, Broker, Server, Minion) Yes (Please label as backward-incompat, and complete the section below on Release Notes) Does this PR fix a zero-downtime upgrade introduced earlier? Yes (Please label this as backward-incompat, and complete the section below on Release Notes) Does this PR otherwise need attention when creating release notes? Things to consider: New configuration options Deprecation of configurations Signature changes to public methods/interfaces New plugins added or old plugins removed Yes (Please label this PR as release-notes and complete the section on Release Notes) Release Notes Ingestion Pre-Aggregation is now supported for MIN, MAX, and COUNT, in addition to SUM. To enable the feature, add an aggregationConfig to the ingestionConfigs of a realtime table config. The format of the config is "aggregationConfigs": [ { "columnName": "destColumn", "aggregationFunction": "MIN(srcColumn)" } ], The destColumn must be in the schema and the srcColumn must not be in the schema. Additionally, all destColumns must be noDictionaryColumns. Documentation After this PR I will add the documentation. -- This is an automated message from the Apache Git Service.
