> At my company I've been experimenting with enabling
> {{hbase.rpc.rows.size.threshold.reject}} on our RegionServers as a protective
> measure, to prevent Java OOMs caused by large Multi requests. This has caused
> issues for some clients using BufferedMutators, which send large batches of
> mutations, sometimes all to a single RegionServer. It the BufferedMutator had
> a way to flush before hitting the RegionServer's
> {{hbase.rpc.rows.warning.threshold}}, then it could get its mutations done
> successfully. This is easy to add.
