cxzl25 opened a new pull request, #9900:
URL: https://github.com/apache/paimon/pull/9900
### Purpose
Both Spark truncate paths create a `BatchTableCommit` and never close it:
- `TruncatePaimonTableWithFilterExec.run()` handles `TRUNCATE TABLE` with or
without a partition spec on the driver.
- `PaimonSparkTableBase.truncateTable` implements Spark's `TruncatableTable`.
`TableCommitImpl.close()` shuts down the underlying commit and its
`maintainExecutor` thread pool, so every `TRUNCATE TABLE` leaked a thread
pool
on the driver. Both call sites now wrap the commit in try/finally, matching
`PaimonFormatTable.withCommit` and the other commit call sites in this
module.
