Generally we see pluses (See 2.5.6.2 Bigger Regions in
http://hbase.apache.org/book/important_configurations.html for the latest
scripture on the topic).  Downsides would be something like compactions run
longer (coarsely, same overall work, just takes longer to complete a region)

I'm not sure I understand the question above Kireet.  You doing merges?
 Yes, you can just change the configs on the cluster and regions will just
grow (will need to rolling restart the cluster to pick up the config.)

Please ask again what you would confirm.
