Yanfei Lei commented on FLINK-29095:
------------------------------------
[~jingge] There is already a [trace
log|https://github.com/apache/flink/blob/master/flink-runtime/src/main/java/org/apache/flink/runtime/state/IncrementalRemoteKeyedStateHandle.java#L252]
when deleting {{{}IncrementalRemoteKeyedStateHandle，{}}}I think we can use
this trace log to debug.
> logging state file deletion

> Key: FLINK-29095
> URL: https://issues.apache.org/jira/browse/FLINK-29095
> Project: Flink
> Issue Type: New Feature
> Components: Runtime / State Backends
> Affects Versions: 1.16.0
> Reporter: Jing Ge
> Assignee: Roman Khachatryan
> Priority: Critical
>
> with the incremental checkpoint, conceptually, state files that are never
> used by any checkpoint will be deleted/GC . In practices, state files might
> be deleted when they are still somehow required by the failover which will
> lead to Flink job fails.
> We should add the log for trouble shooting.
