mayankshriv opened a new pull request #6761:
URL: https://github.com/apache/incubator-pinot/pull/6761
- Added pinot-segment-local module that contains all the segment related
implementations for the existing local Pinot segment.
- Modules that pinot-segment-local depends on:
- pinot-spi
- pinot-segment-spi
- pinot-common: This is temporary and needed as a lot of common utilities
are within pinot-common.
- External libraries: Datasketches,TDigest, HLL, Lucene, larray.
- Modules dependent on pinot-segment-local:
- pinot-core
- pinot-server, pinot-perf: Only in test-scope
Most moves/refactors done via IDE. Manual changes listed below:
- Fix typo in Logger for RealtimeLuceneIndexReaderRefreshThread.
- Moved builder specific util methods from StarTreeUtils to
StarTreeBuilderUtils.
- `shouldRemove()`
- `remove()`
- Made local copy of MAX_DOC_PER_CALL inside of PinotDataBitSetV2, as it is
currently
defined in DocIdSetPlanNode, but segment related code depends on it.
- Made local copy of DEFAULT_TDIGEST_COMPRESSION in
PercentileTDigestValueAggregator,
originally defined in PercentileTDigestAggregationFunction.
- Made local copy of DEFAULT_MAX_ERROR in PercentileEstValueAggregator,
originally defined in
PercentileEstAggregationFunction.
- Split QueryContextRequestUtils into two files, the new one calle
RequestContextConverterUtils
is in pinot-common, as it has utility methods related to classes in
pinot-common.
- Created CustomSerDeUtils class, that has code from ObjectSerDeUtils
related to ValueAggregator.
This is again to avoid pulling in dependencies from pinot-core into
pinot-segment-local.
- Removed reference of Operator in javadoc of EarlyTerminationException, as
it is
was causing reference dependency to pinot-core.
- Renamed SegmentGenerationWithNullValueTest to SegmentWithNullValueTest as
it has test for segment
generation as well as querying, and can only be housed in pinot-core atm.
Moves done to resolve cross dependency issues:
- Following moved to pinot-segment-local utils package:
- IngestionUtils
- TableConfigUtils
- SchemaUtils
- SegmentTestUtils: This depends on AvroSchemaUtil, added dependency on
pinot-avro in test-scope.
- Following moved to pinot-common:
- FilterContext
- ExpressionContext
- FunctionContext
- Predicate
- Following moved to pinot-spi
- ReadMode
- CommonConstants
- ArrayCopyUtils
- BadQueryException moved
- EarlyTerminationException
