Subject [jira] [Commented] (CASSANDRA-7343) CAS contention back off time should be configurable
Date Tue, 08 Jul 2014 17:38:04 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7343?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14055177#comment-14055177

sankalp kohli commented on CASSANDRA-7343:
------------------------------------------

Thanks for the feedback. I will move it down to table level. Regarding having one property
for both SERIAL and LOCAL_SERIAL, I am fine with that since it is at table level and can be
changed easily. 
In case of DC failure, if someone is degrading to LOCAL_SERIAL, they can also change this
value I guess.

> We are currently making the contention call sleep for upto 100 millis. This is not ideal
for all situations specially if you are doing LOCAL_SERIAL. 
> This value should be configurable based on CL.
