Andrew Kyle Purtell commented on HBASE-24436:
---------------------------------------------
By above stated goal of opening as quickly as possible this proposal is
suboptimal compared to leaving things alone and simply changing default
configuration or changing how the store open pools sizes are calculated in some
other way. -1 on this proposal until that is address. Not sure how you'd
address it because it is the lift up to region that is the problem. Please
consider HBASE-24445 (Improve default thread pool size for opening store files)
instead.
> 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
> are some cases that some column families have much more store files than
