xiangfu0 opened a new pull request, #19297:
URL: https://github.com/apache/pinot/pull/19297
Part 1/5 of the split of #19287 (Fix FULL-upsert vector candidate
generation).
## Summary
Groundwork for applying the FULL-upsert valid-document snapshot before
vector candidate
selection (done in part 4/5):
- Extract a shared `computeExactMatches` helper in
`ExactVectorScanFilterOperator` that
unifies the exact top-K and threshold scan paths and can restrict scoring
to an
allowed-document bitmap. When a bitmap is supplied, only allowed document
IDs are read
from the forward index, and IDs beyond the `numDocs` watermark are ignored.
- Introduce `VectorCandidateScope`, an immutable query-scoped candidate
constraint that
owns a single defensive copy of the supplied bitmap.
`ExactVectorScanFilterOperator`
accepts it via a new constructor overload; no production caller passes one
yet, so
behavior is unchanged.
- Report candidate-filter cardinality in the operator's explain output.
- Add filtered-reader coverage for `HnswVectorIndexReader.getDocIds(query,
k, allowed)`.
## Validation
All commands ran with JDK 25.
- `ExactVectorScanFilterOperatorTest`: 16 tests passed (6 new
allowed-document tests).
- `HnswVectorIndexCreatorTest`: 6 tests passed (1 new filtered-reader test).
- Spotless, Checkstyle, and license checks passed.
