CrownChu opened a new pull request, #9127:
URL: https://github.com/apache/paimon/pull/9127
## What is the purpose of the change?
An RLE run covers the half-open interval `[rowId, rowId + n)`. When its end
is exactly equal to `rangeStart`, it has no overlap with the requested sparse
row range and must be skipped. The existing strict `<` boundary can retain that
run and misalign sparse Parquet reads.
## Brief change log
- Change all three affected RLE boundary checks from `<` to `<=`.
- Add a data-evolution regression test covering sparse row positions.
- Verify both a flat column and a repeated/list column at the boundary
positions.
## Verifying this change
```bash
mvn -pl paimon-core -am -DskipITs -Dfast \
-Dtest=DataEvolutionSplitReadTest \
-Dsurefire.failIfNoSpecifiedTests=false test
```
Result: 14 tests passed. Spotless and Checkstyle also passed.
