Date Thu, 02 Feb 2017 12:59:51 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8826?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15849883#comment-15849883

Pavel Trukhanov commented on CASSANDRA-8826:
--------------------------------------------

So what should happen for this feature to get going? Can one just try to implement it or any
more clarifications/discussion needed?

>                 Key: CASSANDRA-8826
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8826
>             Project: Cassandra
>          Issue Type: Improvement
>            Reporter: Robert Stupp
>            Priority: Minor
>
> Aggregations have been implemented in CASSANDRA-4914.
> All calculation is performed on the coordinator. This means, that all data is pulled
by the coordinator and processed there.
> This ticket's about to distribute aggregates to make them more efficient. Currently some
related tickets (esp. CASSANDRA-8099) are currently in progress - we should wait for them
to land before talking about implementation.
> Another playgrounds (not covered by this ticket), that might be related is about _distributed
filtering_.
