[jira] [Commented] (FLINK-12193) Send TM "can be released status" with RM heartbeat

    [ https://issues.apache.org/jira/browse/FLINK-12193?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17219619#comment-17219619 ]

------------------------------------------

I'm concerned how well this would work if the heartbeat interval is larger.

> We introduced a conditional release of Task Executor in Resource Manager in FLINK-10941. At the moment RM directly asks TE every release timeout whether it can be released (all depending consumers are done). We can piggyback TE/RM heartbeats for this purpose. In this case, we do not need additional RPC call to TE gateway and could potentially release TE quicker.
