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.
Thoughts?
