Junhong Xu commented on HBASE-24436:
------------------------------------
I think we have reached an agreement on creating the thread pool at the region
level. The difference is about the parallelism, which is based on stores or
store files. [~filtertip] What do you think about the solution Andrew provide
above, which is creating the thread pool based on store file count with upper
bound, which will be faster, right? Any other concerns?
> 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
> others( maybe that's the life, right? ). So in that case, some Stores have
> beed done quickly while others are struggling.We should share the thread pool
