-----------------------------------
Hi [~yuzhih...@gmail.com], why this should be a bug? I think
{{snapshotCloseableRegistry}} will be empty in this case, so it doesn't need to
be closed...
> Unclosed snapshotCloseableRegistry in
> RocksDBKeyedStateBackend#FullSnapshotStrategy#performSnapshot

> {code}
> final CloseableRegistry snapshotCloseableRegistry = new
> CloseableRegistry();
> if (kvStateInformation.isEmpty()) {
> if (LOG.isDebugEnabled()) {
> LOG.debug("Asynchronous RocksDB snapshot performed on empty keyed
> state at {}. Returning null.",

> {code}
> If the method returns in the above if block, snapshotCloseableRegistry is not
> closed.
