----------------------------------------------

So we could have about 6% performance gain in YCSB? It is a bit surprise to me, 
I didn't think we could increase read/write performance, we could just save 
lots of time for the background tasks, such as flush and compaction...

I think part of it is due to split storms happening during the run. Splits were 
taking longer to complete on the hboss/renames cluster, causing some requests 
to timeout for longer. Another observation was that the hboss/renames cluster 
had more regions at the end of the run. Maybe because compactions were much 
slower, the split threshold was being met more often, leading to more splits. 

Snapshots recovery is another area we could see improvements, when dealing with 
snapshots of tables with hundreds to thousands of regions. We are doing more 
tests to consolidate numbers, will post more details here later.

> Open a separated jira to track the work since it can not be fully included in 
> HBASE-24749.
> I think this could be a landed prior to HBASE-24749, as if this works, we 
> could have different implementations for tracking store file list.
