Subject [jira] [Commented] (CASSANDRA-4775) Counters 2.0
Date Fri, 05 Apr 2013 16:53:18 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4775?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13623787#comment-13623787

Jonathan Ellis commented on CASSANDRA-4775:
-------------------------------------------

bq. The implementation becomes a fair bit more complicated

I'm not really sure about that.  Both with this and the above design [1], we do have more
complexity on read/reconcile, but we trade that for zero special cases at the storage engine,
which is a huge win.

> 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
