>             Project: Flink
>          Issue Type: Bug
>          Components: Runtime / State Backends
>    Affects Versions: 2.1.0

>            Priority: Major
>             Fix For: 2.0.0

> After https://issues.apache.org/jira/browse/FLINK-26050, Flink RocksDB may schedule manual compaction asynchronously, but if a failover occurs at this time, RocksDB will need to wait for the manual comparison to complete before it can close. This may result in a very long time for task cancellation, affecting the time for task recovery.
> {code:java}
> // After this function call, CompactRange() or CompactFiles() will not
> // run compactions and fail. Calling this function will tell outstanding
> // manual compactions to abort and will wait for them to finish or abort
> // before returning.
> virtual void DisableManualCompaction() = 0; {code}
> The solution is relatively simple. We can manually call _DisabManulCompaction_ during db close to abort the running ManulCompaction, which can accelerate db close faster.
