CrownChu opened a new pull request, #8702:
URL: https://github.com/apache/paimon/pull/8702
## Purpose
`paimon-eslib` currently activates automatically on JDK 11+ and resolves
ESLib artifacts from a mutable GitHub Raw repository path. This couples the
default Paimon build to an external repository.
ESLib 1.0.7 now provides immutable, Lucene-specific artifacts and supports
int8 HNSW.
## Changes
- Update ESLib dependencies to:
- `eslib-core-lucene9:1.0.7`
- `eslib-simdvec-lucene9:1.0.7`
- Pin the Maven repository to the immutable `eslib-1.0.7` tag.
- Make `paimon-eslib` opt-in through `-Ppaimon-eslib`.
- Add a dedicated JDK 11 workflow for ESLib tests.
- Support `m` and `ef_construction` for `int8_hnsw`.
- Add regression coverage verifying that int8 HNSW parameters reach the
Lucene codec.
- Document the ESLib source and artifact repositories.
`paimon-eslib` remains a thin JAR and does not bundle ESLib or Lucene
classes.
## Validation
- `mvn -T 2C -B -ntp clean install -DskipTests -Ppaimon-eslib -pl
paimon-eslib -am`
- `mvn -B -ntp verify -Ppaimon-eslib -pl paimon-eslib`
- 71 tests passed
- Verified that only ESLib 1.0.7 Lucene 9 artifacts are resolved.
- Verified that the generated Paimon JAR contains no ESLib or Lucene classes.
- Verified that `paimon-eslib` is not activated by the default JDK 17
reactor.
