> On busy spurts we can see regionservers start to see large queues for 
> compaction. It's really hard to tell if the server is queueing a lot of 
> compactions for the same region, lots of compactions for lots of regions, or 
> just falling behind.
> For flushes much the same. There can be flushes in queue that aren't being 
> run because of delayed flushes. There's no way to know from the metrics how 
> many flushes are for each region, how many are delayed. Etc.
> We should add either more metrics around this ( num per region, max per 
> region, min per region ) or add on a UI page that has the list of compactions 
> and flushes.
> Or both.
