   This issue was reviewed as part of the JIRA-migrated backlog triage (HUDI-9648).
   
   **Findings: still open.**
   
   The description is well specified - two APIs on `HoodieBackedTableMetadata`, one keyed on the record key alone (probing all partitioned RLI file groups) and one that also carries the partition key as a targeting hint. Neither those APIs nor the `PartitionedRecordLevelIndexPrefixKey` / `PartitionedRecordLevelIndexKey` `RawKey` types exist on `master`, so this is unstarted.
   
   Worth linking to #17308 (HUDI-8517, extend secondary index to work as a non-global index): both tickets are about the record-level index stopping being implicitly global, and the secondary index cannot carry partition information at all today because `HoodieSecondaryIndexInfo` has a single `isDeleted` field. A shared decision about how partition context is represented in MDT keys and values would serve both.
   
   Also note the issue type is Bug but the content is a feature request - worth correcting so it is not counted as a defect.
   
   Keeping this open.
