[jira] [Closed] (FLINK-25598) Changelog materialized state discarded on failure

     [ https://issues.apache.org/jira/browse/FLINK-25598?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Roman Khachatryan closed FLINK-25598.
-------------------------------------
    Resolution: Invalid

After creating the issue I realized that RocksDB backend starts using any file only after all of them are uploaded; and it's very unlikely that any failure will happen afterwards.
