[jira] [Commented] (FLINK-3841) RocksDB statebackend creates empty dbs for stateless operators

["Aljoscha Krettek (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-3841?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15261719#comment-15261719 ] 

Aljoscha Krettek commented on FLINK-3841:
-----------------------------------------

You're absolutely right. Should probably check this in {{getPartitionedState}} and create the db if it doesn't exist.

[~gyfora] Do you want to take it or should I quickly fix it?

> Even though they are not checkpointed there is always an open RocksDB database for all operators if the Rocks backend is set. I wonder if it would make sense to lazy initialize the dbs instead of doing it in the initializeForJob method.
