> Key: FLINK-6475
> URL: https://issues.apache.org/jira/browse/FLINK-6475
> Project: Flink
> Issue Type: Bug
> Components: State Backends, Checkpointing
> Reporter: Stefan Richter
> Assignee: Stefan Richter
> Priority: Critical
> Fix For: 1.3.0
>
>
> The implementation of incremental checkpoints in RocksDB mistakenly holds the
> {{asyncSnapshotLock}} during the whole async part, effectively blocking all
> asynchronous processing. Holding the lock is only required in the synchronous
> part, while the backup to local FS is running.
