Elliott Clark updated HBASE-15470:
----------------------------------
Affects Version/s: 1.2.0
> Add a setting for Priority queue length
> ---------------------------------------
>
> Key: HBASE-15470
> URL: https://issues.apache.org/jira/browse/HBASE-15470
> Project: HBase
> Issue Type: Improvement
> Components: IPC/RPC, Region Assignment
> Affects Versions: 1.2.0
> Reporter: Elliott Clark
> Assignee: Elliott Clark
>
> Meta can have very different request rates than any other region. We shouldn't use the same call queue length.
> For example:
> If a normal request takes 100ms ( long scan or large get )
> but a call to meta is all in memory so it takes < 1ms
> So a call queue length of 100 represents multiple seconds of work for normal requests, but less than a second for meta.
