### Purpose Fix #9595. For Chain Tables, `ChainTablePartitionExpire` may delete expired partitions from the Snapshot branch during a Delta commit, creating a new Snapshot-branch metadata snapshot. However, automatic snapshot expiration currently only runs for the committing Delta branch. As a result, old Snapshot-branch snapshots may remain and continue referencing expired files. ### Changes When the current branch is the configured Chain Table Delta branch, also expire snapshots on the configured Snapshot branch after the normal Delta-branch expiration. The maintenance order remains: 1. Partition expiration 2. Delta-branch snapshot expiration 3. Snapshot-branch snapshot expiration ### Tests Added a regression test covering: `Delta commit -> ChainTablePartitionExpire -> Snapshot partition deletion -> new Snapshot metadata snapshot -> Snapshot snapshot expiration` The test verifies that expired Snapshot partitions are removed and only the latest Snapshot-branch snapshot is retained. -- This is an automated message from the Apache Git Service.
