Lars Hofhansl commented on HBASE-12988:
---------------------------------------
[~stack], this is the issue I was mentioning. Check out the number from June
1st above (that was a test with maximum parallelism - not correct, but shows
the potential), 3 or 5 way I think.
The later number are for something that works, namely for parallelizing across
regions.
> [Replication]Parallel apply edits across regions
