Description

In splitStoreFiles(...) we create a new thread pool with as many threads as there are files to split.
We should be able to do better. During times of very heavy write loads there might be a lot of files to split and multiple splits might be going on at the same time on the same region server.

Sub-Tasks

• SpliTransaction: Log number of files to be split: Closed
• SplitTransaction: Add metrics: Closed
