Stephen0421 opened a new pull request, #10014:
URL: https://github.com/apache/paimon/pull/10014
## Purpose
Add Flink `remove_orphan_blobs` (action + procedure) for unreferenced
primary-key `.managed.blob` packs, stacked on the landed core cleaner and Spark
procedure.
- `local` reuses `LocalManagedBlobOrphanFilesClean`
- `distributed` freezes the validated used-pack set with `executeAndCollect`
before listing candidates, then filters with a captured `HashSet`. Deletion
does not reconnect the sidecar/mark DAG, so a lost used-pack shuffle cannot
drop a live pack
- Abort if the used-pack set changes (`SKIP_MANAGED_BLOB_GC`)
- `database.*` runs tables one after another so one table’s freeze cannot
execute another table’s uncommitted deletion graph
- Bounded used/candidate joins keep `ALL_EXCHANGES_BLOCKING`
- Docs: `docs/docs/flink/procedures/repair.md`, procedure index, and
`blob-storage.md`
