> It seems that currently there are two places should not employ the {{synchronized}} to describe {{pendingFilesPerCheckpoint}}, as it is only restored state object for checkpoint and no sharing of the data-structure between different threads, as follows. {code} private void handleRestoredRollingSinkState(RollingSink.BucketState restoredState) {
> ...
> synchronized (restoredState.pendingFilesPerCheckpoint) {
> restoredState.pendingFilesPerCheckpoint.clear();
> }
> ...
> }{code} and {code}private void handleRestoredBucketState(State<T> restoredState) {
> ...
> synchronized (bucketState.pendingFilesPerCheckpoint) {
> bucketState.pendingFilesPerCheckpoint.clear();
> }
> } {code}
> Hi, [~kkl0u]. Is there any other stuff shoud add here ? Would you mind have a more thorough look in this class ?
