Subject [jira] [Resolved] (CASSANDRA-7326) counter: update delete Command conflict
Date Fri, 30 May 2014 12:42:01 GMT

]

Aleksey Yeschenko resolved CASSANDRA-7326.
------------------------------------------

    Resolution: Not a Problem

This is the intended behavior. A deleted counter cannot be reused, because this operation
cannot be implemented deterministically.
