clintropolis opened a new pull request, #19579: URL: https://github.com/apache/druid/pull/19579
### Description Follow-up to #19460, this PR introduces the writer side stuff so that the segments can actually be created. changes: * adds `BaseTableProjectionSpec` interface to capture the operator facing shape of V10 base table schemas * adds `ClusteredValueGroupsBaseTableSchema` implementation for ingesting clustered segments * adds `DataSchema.baseTable`, a `BaseTableProjectionSpec` which when set puts the DataSchema into a new mode where the majority of the schema is defined via the baseTable, rejecting other top level fields * adds `DataSchema.segmentGranularity` to use when `baseTable` is set, which captures the segment granularity and intervals (query granularity is defined by the baseTable) * adds `AdaptedBaseTableProjectionSpec` implementation for converting classic `DataSchema` fields to a `BaseTableProjectionSpec` * adds `OnHeapClusteredBaseTable`, `OnHeapClusterGroup` used by `OnHeapIncrementalIndex` to build clustered segments * adds `IndexMergerV10.makeClusteredIndexFiles` which merges and builds clustered v10 segments * `Sink`/`BatchAppenderator`/`StreamAppenderator` wiring for clustered segments so that the cluster group tuples appear on the `DataSegment` * known issues: unbounded, no aggregate projections, no compaction support, no time ordered cursor support -- This is an automated message from the Apache Git Service.
