Ariel Weisberg commented on CASSANDRA-14407:
--------------------------------------------
Note here, that speculative retry for writes doesn't have a separate config
option, it uses the same config as read. We should evaluate if that is a good
idea.
> Transient Replication: Add support for correct reads when transient
> replication is in use

> Key: CASSANDRA-14407
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14407
> Project: Cassandra
> Issue Type: Sub-task
> Components: Coordination
> Reporter: Ariel Weisberg
> Assignee: Blake Eggleston
> Priority: Major
> Fix For: 4.0
>
>
> Digest reads should never be sent to transient replicas.
> Mismatches with results from transient replicas shouldn't trigger read repair.
> Read repair should never attempt to repair a transient replica.
> Reads should always include at least one full replica. They should also
> prefer transient replicas where possible.
> Range scans must ensure the entire scanned range performs replica selection
> that satisfies the requirement that every range scanned includes one full
> replica.
