                 URL: https://issues.apache.org/jira/browse/FLINK-25770
             Project: Flink

            Reporter: Jingsong Lee
            Assignee: Jingsong Lee
             Fix For: table-store-0.1.0


The deletion in MergeTreeWriter.updateCompactResult dose not consider upgrade case, the upgrade file is required by previous snapshot and following snapshot, we should ensure:
1. This file is not the output of upgraded.
2. This file is not the input of upgraded.

Otherwise, the file will be deleted incorrectly.
