Anoop Sam John commented on HBASE-24436:
----------------------------------------
bq.which is creating the thread pool based on store file count with upper
bound, which will be faster,
Ya that would be better. Agree. Looking forward for the patch. How achieving
this. Will be bit tricky as we have multi threaded at 2 levels (HStore open
which list the store files and then another thread pool for opening store
files).
> The store file open and close thread pool should be shared at the region level

> For now, we provide threads per column family evenly in general, but there
