> Key: FLINK-7700
> URL: https://issues.apache.org/jira/browse/FLINK-7700
> Project: Flink
> Issue Type: Bug
> Components: State Backends, Checkpointing
> Affects Versions: 1.4.0, 1.3.2
> Reporter: Aljoscha Krettek
> Assignee: Aljoscha Krettek
> Priority: Blocker
> Fix For: 1.4.0, 1.3.3
>
>
> {{RocksDBAggregatingState.mergeNamespaces(...)}},
> {{RocksDBReducingState.mergeNamespaces(...)}}, and
> {{RocksDBListState.mergeNamespaces(...)}} don't remove state from the old
> location when merging. This means that merged state will never be cleaned up
> and will accumulate.
