Jean-Marc Spaggiari commented on HBASE-11780:
---------------------------------------------

+1 for that. I worked on the side to such a balancer based on the overall server load. Never got a chance to finish it, but I like the idea. Current version simply statically weight the RS and balance the regions based on that, but goal was to have this weight dynamic and adjusted slowly based on the server load.

> In some situations with heterogeneous hardware it might be helpful to take in account the available resources such as RAM, cores or spindles before for the region assignment. A form of weight per RS might be an initial approach but for also a limit of open regions in a RS or maximum open store files could be used.
