[jira] [Commented] (CASSANDRA-6662) Sort/reconcile cells in ArrayBackedSortedColumns only when an accessor is called

    [ https://issues.apache.org/jira/browse/CASSANDRA-6662?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13893005#comment-13893005 ] 

Aleksey Yeschenko commented on CASSANDRA-6662:
----------------------------------------------

Once implemented, do we actually *need* TreeMapBackedSortedColumns anymore?

> To avoid poor performance with huge numbers of cells added out of order (which should be rare, but *can* happen with certain batch scenarios) we should make ABSC only sort/reconcile its cells when an actual accessor is actually called, delaying sorting until the very end.
