Roman Khachatryan reassigned FLINK-25511:
-----------------------------------------
Assignee: Roman Khachatryan
> Pre-emptively uploaded changelog not discarded up if materialized before
> checkpoint
> -----------------------------------------------------------------------------------
>
> Key: FLINK-25511
> URL: https://issues.apache.org/jira/browse/FLINK-25511
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Checkpointing, Runtime / State Backends
> Affects Versions: 1.15.0
> Reporter: Yuan Mei
> Assignee: Roman Khachatryan
> Priority: Major
> Fix For: 1.16.0
>
>
> This is related to Garbage Collection.
> The problem is more severe than FLINK-25512 because there is leftover after
> materialization truncation each time (if pre-emptive uploads are enabled).
> However, the probability can still be not high because of grouping of
> backends into a single file (so only if ALL the backends on TM materialize
> semi-simultaneously then it happen).
