### Feature Request / Improvement Adds a `PostCommitHook` plugin interface to `IcebergSink` that is invoked after each successful Iceberg commit. This enables use cases like updating table properties, triggering notifications, recording metrics, or synchronizing external metadata stores. ### Query Engine Flink ### Motivation After a successful Iceberg commit, users often need to perform additional operations (e.g., write watermark metadata to table properties, notify downstream systems, update external catalogs). Currently there is no extension point -- users must subclass `IcebergCommitter` and override `commit()`, which requires forwarding many constructor arguments through the subclass chain. This adds a `PostCommitHook` that is called after `operation.commit()` with the snapshot ID and snapshot summary. The hook runs in the committer's context and has access to all commit metadata. ### Changes - New: `PostCommitHook.java` -- `@FunctionalInterface` with a single method: `void afterCommit(long snapshotId, Map<String, String> summary)` - Modified: `IcebergCommitter` -- accepts optional hook, invokes it after successful commit - Modified: `IcebergSink.Builder` -- new `postCommitHook()` method, passed through to committer ### Compatibility - No behavioral change when the hook is not set (null default) - No changes to public API signatures of existing methods - Fully backward compatible ### Willingness to contribute - [x] I can contribute this improvement/feature independently - [x] I would be willing to contribute this improvement/feature with guidance from the Iceberg community - [ ] I cannot contribute this improvement/feature at this time -- This is an automated message from the Apache Git Service.
