Subject [jira] [Updated] (CASSANDRA-8094) Heavy writes in RangeSlice read requests
Date Thu, 09 Oct 2014 16:59:34 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-8094?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Minh Do updated CASSANDRA-8094:
-------------------------------
    Description: 
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.
