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

["Alain RODRIGUEZ (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-4775?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13812852#comment-13812852 ] 

Alain RODRIGUEZ commented on CASSANDRA-4775:
--------------------------------------------

{quote}Remove the replicate_on_write option and switch to a locked/retryable RMW.{quote}

What will this imply for the final user ? No more over-counts due to retry, no more read on write ? Any disadvantage switching to those locked RMW ?

Counters are very useful, but also really hard to handle because of their specific characteristics. I hope that some of them will be removed here.

{quote}This (+some optimizations) is what we are going for in 2.1, and will be ready soon-ish (returning back to this after one issue).{quote}

How is this going ?

> 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
