I'm using much larger region size (~200 GB) and it's not a real problem if
you're controlling compactions ; am I right ? It allows a strong reduction
of number of regions, and thus less memstores, smoother flushes, etc. Of
course, as usual it might depends on your workload but can perfectly fit
some needs IHMO.
