ryan rawson commented on HBASE-3507: ------------------------------------ how frequently would you move regions? Moving a highly loaded region under load might be more disruptive than leaving where it is... Using a more sophisticated algorithm that uses a decaying moving average over some period of time seems like that might have a better impact. For example do you move a region because it gets hot for 30 seconds? 1 minute? 5 minutes? 10 minutes even? I'm not sure where the line is, but it seems like the goal should be to move regions for persistent high long term load, not transient spikes.
