[jira] [Commented] (CASSANDRA-8094) Heavy writes in RangeSlice read
requests
[ https://issues.apache.org/jira/browse/CASSANDRA-8094?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15269018#comment-15269018 ]
Sam Tunnicliffe commented on CASSANDRA-8094:
--------------------------------------------
Coming back to look at this now, I think that using {{extensions}} to persist the param is just too hacky to be considered a reasonable approach. Given that, we should either defer this ticket until 4.0 or prioritize CASSANDRA-11382, using this as a driver towards an implementation.
> Heavy writes in RangeSlice read requests
> ------------------------------------------

> Key: CASSANDRA-8094
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8094
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Minh Do
> Assignee: Sam Tunnicliffe
> Labels: lhf
> Fix For: 3.x
>
>
> RangeSlice requests always do a scheduled read repair when coordinators try to resolve replicas' responses no matter read_repair_chance is set or not.
> Because of this, in low writes and high reads clusters, there are very high write requests going on between nodes.
> We should have an option to turn this off and this can be different than the read_repair_chance.
