Explore adding replay ID for counters
-------------------------------------
Key: CASSANDRA-2783
URL: https://issues.apache.org/jira/browse/CASSANDRA-2783
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Sylvain Lebresne
If a counter write returns a TimeoutException, the client cannot retry its
write without risking an overcount.
One idea to fix this would be to allow the client to specify a replay ID with
each counter write unique to the write. If the write timeout, the client would
resubmit the write with the same replay ID and the system would ensure that
write is only replayed if the previous write was not persisted.
Of course, the last part of this ("the system would ensure ...") is the hard
part. Still worth exploring I believe.
