[jira] [Comment Edited] (FLINK-15507) Activate local recovery for RocksDB backends by default

    [ https://issues.apache.org/jira/browse/FLINK-15507?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17115767#comment-17115767 ]

PR submitted. I have run all UTs and e2e tests, and tried the WordCount streaming job with default settings to make sure the local recovery is activated by checking the local state directory.

Also, I have checked canceling a checkpoint with local recovery activated, and there is no file leak on disk, which is part of the goal for FLINK-8871.

> For the RocksDB state backend, local recovery has no overhead when incremental checkpoints are used. 
> It should be activated by default, because it greatly helps with recovery.
