>             Fix For: 3.x
> A ticket to aggregate issues for removal of some of the counters limitations we currently
> 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|]
and [this|]
> This seems to be a pre-requisite for CASSANDRA-9778.
