> Key: FLINK-29916
> URL: https://issues.apache.org/jira/browse/FLINK-29916
> Project: Flink
> Issue Type: Bug
> Components: Table Store
> Affects Versions: table-store-0.3.0, table-store-0.2.2
> Reporter: Caizhi Weng
> Assignee: Caizhi Weng
> Priority: Major
> Labels: pull-request-available
> Fix For: table-store-0.3.0, table-store-0.2.2
>
>
> Current constructor of {{Levels}} class contains the following code:
> {code:java}
> this.level0 = new
> TreeSet<>(Comparator.comparing(DataFileMeta::maxSequenceNumber).reversed());
> {code}
> However when two or more jobs writing the same bucket, they may produce files
> containing the same sequence number. If two files have the same
> {{maxSequenceNumber}}, one of them will be mistakenly ignored by {{TreeSet}}.
