> Lift some counters limitations in C* 3.X

>                 Key: CASSANDRA-9810
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9810
>             Project: Cassandra
>          Issue Type: Improvement
>            Reporter: Aleksey Yeschenko
>             Fix For: 3.x

>
> A ticket to aggregate issues for removal of some of the counters limitations 
> we currently have:
> 1. Counters are not reusable after deletion. It's true that deletion doesn't 
> commute, and an increment coming soon after a deletion would lead to 
> undefined behavior, but the current behavior is the result of bug in 1.1. We 
> should revert CASSANDRA-7346
> 2. Once that is done, we can start allowing to mix counters and non-counters 
> in the same tables. For read requests it means data locality, being able to 
> satisfy more requests with a single query. We would still be forbidding 
> updating counter columns and regular columns in a single {{UPDATE}}, however, 
> and would not allow counter updates in {{INSERT}}
> See CASSANDRA-8878 for some discussion of the subject. In particular, 
> [this|https://issues.apache.org/jira/browse/CASSANDRA-8878?focusedCommentId=14346748&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14346748]

>  comments.
> This seems to be a pre-requisite for CASSANDRA-9778.
