[jira] [Commented] (CASSANDRA-4775) Counters 2.0

    [ https://issues.apache.org/jira/browse/CASSANDRA-4775?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13653232#comment-13653232 ] 

Edward Capriolo commented on CASSANDRA-4775:
--------------------------------------------

Random idea: Why not have separate memtable and separate commit logs for counters. You can not mix columns and counter columns anyway and they work very differently so lifting them completely out of the normal storage layer might help.

> The existing partitioned counters remain a source of frustration for most users almost two years after being introduced.  The remaining problems are inherent in the design, not something that can be fixed given enough time/eyeballs.
> Ideally a solution would give us
> - similar performance
> - less special cases in the code
> - potential for a retry mechanism
