[jira] [Commented] (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=17009966#comment-17009966 ] 

Yun Tang commented on FLINK-15507:
----------------------------------

A known issue when we enable local recovery by default is that local state cannot be cleared if no checkpoint ever completed, which is one of the goals 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.
