T Jake Luciani commented on CASSANDRA-2495:
-------------------------------------------
CASSANDRA-2034 does improve this a bit, since we know a hint was stored for the
timed out replica(s).
> Add a proper retry mechanism for counters in case of failed request

> Contrarily to standard insert, counter increments are not idempotent. As
> such, replaying a counter mutation when a TimeoutException occurs could lead
> to an over-count. This alone limits the use cases for which counters are a
> viable solution, so we should try to come up with a mechanism that allow the
> replay of a failed counter mutation without the risk of over-count.
