[jira] [Created] (CASSANDRA-9811) Tie counter shards' logical clock value to timestamps

Aleksey Yeschenko created CASSANDRA-9811:
--------------------------------------------

             Summary: Tie counter shards' logical clock value to timestamps
                 Key: CASSANDRA-9811
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9811
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Aleksey Yeschenko
            Assignee: Aleksey Yeschenko
             Fix For: 3.x


CASSANDRA-6506 will get rid of counter shards, turning them into elements of a map. And we'll be using the logical clock values as map element timestamps.

To avoid unpleasant initial performance (being unable to perform certain sstable optimisations on the read path), we should switch the shards to use {{max(timestamp, clock + 1)}} now, in advance of CASSANDRA-6506 switch.
