> 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.
