> ---------------------------------------------------
>                 Key: HBASE-13101
>                 URL: https://issues.apache.org/jira/browse/HBASE-13101
>             Project: HBase
>          Issue Type: Brainstorming
>          Components: regionserver
>            Reporter: Nick Dimiduk
> We should protect a region server from poorly designed/implemented clients/schemas that
result in a "hotspot" which overwhelms a single machine. A client that creates a new connection
for each request is an example of this case, where META gets completely flooded and kills
the RS. Master diligently brings it up on another host, which sends the traffic along to the
next victim, and will slowly bring down the whole cluster.
> My suggestion is rate-limiting per client, implemented at the RPC level, but I'm looking
for other suggestions.
