--------------------------------------------------------------
[~Yanfei Lei] Thanks for your reply.
I don't think the current pr will fix this, and I verified that it does.
The reason is still that the filter operator confirm() method will delete the
local changelog file of the window operator, because the window operator file
is not registered at this time.
For this problem, I think of two possible solutions:
Method 1. Change the logic of LocalChangelogRegistryImpl and add a mapping
relationship between operator and file. When confirm() cleans up, only the
files of its own operator are cleaned up;
Method 2. In LocalChangelogRegistryImpl#discardUpToCheckpoint(), change
entry.f1 < upTo to entry.f1 < upTo -1.
Compare the two solutions: method 1 has relatively large changes; method 2 is a
trick method with small changes, but it is not easy to understand. At the same
time, there will be one more checkpoint file storage occupation. WDYT?

> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing, Runtime / State Backends
> Affects Versions: 1.17.0
> Reporter: Yanfei Lei
> Assignee: Yanfei Lei

> Labels: pull-request-available
> Attachments: tm-log_fail_cl_local_recovery.txt

> If TM is materialized before receiving confirm(), the previously uploaded
> queue in `FsStateChangelogWriter` will be cleared, so the local files of the
> completed checkpoint will not be registered again, while the JM owned files
> are registered before confirm(), and do not depend on the uploaded queue, so
> the local files are deleted, and the DFS files are still there.
>
> We have encountered the following situation, the job cannot find the local
> recovery files, but can restore from the DFS files:
