>                 Key: CASSANDRA-12252
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12252
>             Project: Cassandra
>          Issue Type: Improvement
>            Reporter: Carl Yeksigian
>            Assignee: Carl Yeksigian
>            Priority: Minor
> We should properly support read repair and speculative retry for EACH_QUORUM 
> reads.
> To support these, we need to make sure that we count responses for each DC 
> separately, so that we can properly monitor the number of responses from 
> each. For speculative retry, we should try to replace each host that we are 
> retrying with one in the same DC; that will make sure that we actually have 
> the correct responses at the end if the speculative retries are successful.
