Subject load balancing considerations
Date Sat, 31 Jul 2010 22:18:23 GMT
Hi,
Currently load balancing only considers region count.
See ServerManager.getAverageLoad()

I think load balancing should consider the following three factors for each
RS:
1. number of regions it hosts
2. number of requests it serves within given period
3. how close usedHeap is to maxHeap

Please comment how we should weigh the above three factors in deciding the
regions to offload from each RS.

Thanks
