---------------------------------
Hi Bing,
Thanks for sharing your thoughts on this. Throttling TPS/throughput is another
interesting area to work on. Agree with you that META should be too heavy to
save our little blacklist. Maybe ZK would be a nice choice. I'm also working on
a pluggable RpcScheduler (HBASE-8884), hopefully we can simply implement a
customized scheduler, which loads configruation from ZK and perform banning and
throttling.
> Region level read/write degradation

> Key: HBASE-8801
> URL: https://issues.apache.org/jira/browse/HBASE-8801
> Project: HBase
> Issue Type: New Feature
> Reporter: Chao Shi
>
> We would like to propose a tool for HBase administrators to disable read
> and/or write for single region temporarily.
> Our HBase table at weibo.com is accessed by many clients. We have experienced
> the following outage: due to bugs of user code, a small number of regions are
> reading at very high rate. Requests to other regions at the same RSs are
> affected. In such scenario, the admin would like to temporarily set the
> region to write-only (only forbids reads so writes can still being served).
