Subject [jira] [Commented] (CASSANDRA-8969) Add indication in cassandra.yaml that rpc timeouts going too high will cause memory build up
Date Wed, 23 Mar 2016 15:01:25 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8969?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15208544#comment-15208544
] 

Jeremy Hanna commented on CASSANDRA-8969:
-----------------------------------------

Sorry about the lag in responsiveness on my part.  The idea was that if you set it to 2x,
then you could potentially have 2x in-flight requests being kept in memory on the server in
cases where requests get queued up.  I think that's not immediately obvious to people who
increase it to just avoid client-side timeouts.

> It would be helpful to communicate that setting the rpc timeouts too high may cause memory
problems on the server as it can become overloaded and has to retain the in flight requests
in memory.  I'll get this done but just adding the ticket as a placeholder for memory.
