> Key: FLINK-28582
> URL: https://issues.apache.org/jira/browse/FLINK-28582
> Project: Flink
> Issue Type: Bug
> Components: Table Store
> Affects Versions: table-store-0.2.0
> Reporter: Caizhi Weng
> Assignee: Caizhi Weng
> Priority: Blocker
> Labels: pull-request-available
> Fix For: table-store-0.2.0
>
>
> Currently `FileStoreCommitImpl` only checks for conflicts by checking the
> files we're going to delete (due to compaction) are still there.
> However, consider two jobs committing into the same LSM tree at the same
> time. For their first compaction no conflict is detected because they'll only
> delete their own level 0 files. But they will both produce level 1 files and
> the key ranges of these files may overlap. This is not correct for our LSM
> tree structure.
