Re: [I] Implement: Metadata based bloom index - read path [hudi]

nsivabalan commented on issue #14910:
URL: https://github.com/apache/hudi/issues/14910#issuecomment-4795280873

   This task appears to have been implemented in master. The metadata-table bloom index read path is in place:
   
   - `SparkHoodieBloomIndexHelper` reads bloom filters from the MDT `bloom_filters` partition (uses `HoodieMetadataPayload.getBloomFilterIndexKey` + `MetadataPartitionType.BLOOM_FILTERS`).
   - `HoodieMetadataBloomFilterProbingFunction` is the dedicated probing function for the read path.
   - Behavior is controlled by `hoodie.bloom.index.use.metadata` (`HoodieIndexConfig.BLOOM_INDEX_USE_METADATA`).
   
   Relevant commits: HUDI-1295 (#4352, initial implementation), HUDI-3807 (#5268, config gate), HUDI-5534 (#7642, lookup optimization). If there's still scope remaining under HUDI-2701, could the description be updated to capture what's left? Otherwise this can likely be closed.
