> After HBASE-18023 we warn if the number of operations in a multi operation
> exceeds a threshold. This is meant to catch potential performance problems or
> abusive clients. However while testing simple replication scenarios we have
> observed frequent warnings issued as the sink applies received edit batches.
> I think we want to either introduce a separate threshold for warning about
> RPC submitted by the replication client or exclude ops submitted by the sinks
> entirely. Not sure distinguishing the replication client from normal clients
> is possible yet.
