Ted Yu commented on HBASE-4365:
-------------------------------
I understand the proposal provides better heuristic for determining region size.
My comment about load balancer was assuming there're many tables in the cluster.
My second comment originated from our practice of pre-splitting tables. It is
possible that _R_ == _5S_ would be reached soon after the creation of the table
for small-medium sized cluster.

> A few of us were brainstorming this morning about what the default region
> size should be. There were a few general points made:
> - in some ways it's better to be too-large than too-small, since you can
> always split a table further, but you can't merge regions currently
> - with HFile v2 and multithreaded compactions there are fewer reasons to
> avoid very-large regions (10GB+)
> - for small tables you may want a small region size just so you can
> distribute load better across a cluster
> - for big tables, multi-GB is probably best
