Matt Corgan commented on HBASE-5304:
------------------------------------
This would be useful for time series data. Let's say you split a region every
2 weeks. The current split policy would be back in time 1 week ago. It would
be better if it split at the current time and just let the old region go to
sleep (maybe it gets a few more inserts from lagging clients). Or you could
get more intricate and split on nice rounded hour or day intervals.
