             Summary: [Umbrella] Improve throttling feature for production usage
                 Key: HBASE-16707
                 URL: https://issues.apache.org/jira/browse/HBASE-16707
             Project: HBase
          Issue Type: Umbrella
            Reporter: Guanghao Zhang


HBASE-11598 add rpc throttling feature and did a great initial work there. We plan to use
throttling in our production cluster and did some improvements for it. From the user mail
list, I found that there are other users used throttling feature, too. I thought it is time
to contribute our work to community, include:
1. Add shell cmd to start/stop throttling.
2. Add metrics for throttling request.
3. Basic UI support in master/regionserver.
4. Handle throttling exception in client.
5. Add more throttle types like DynamoDB, use read/write capacity unit to throttle.
6. Support soft limit, user can over consume his quota when regionserver has available capacity
because other users not consume at the same time.
7. ... ...

I thought some of these improvements are useful. So open an umbrella issue to track. Suggestions
and discussions are welcomed.
