[jira] [Commented] (CASSANDRA-14727) Transient Replication:
EACH_QUORUM not implemented
[ https://issues.apache.org/jira/browse/CASSANDRA-14727?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16613904#comment-16613904 ]
Ariel Weisberg commented on CASSANDRA-14727:
--------------------------------------------
Is this a relatively simple change to the selector in ReplicaPlans? All we have to do is assemble a quorum inside each DC and return that list as the head?
Speculation writes to all transient replicas so we don't need to fix speculation right now.

> Transient replication cannot presently handle EACH_QUORUM consistency; reads and writes should currently fail, though without good error messages. Not clear if this is acceptable for GA, since we cannot impose this limitation at Keyspace declaration time.
