Hey, I've see that setting writeToWAL(false) boosts up the writes like crazy. I was just thinking having MuiltipleWAL on HBase. I understand that this is a consideration in BigTable paper that a WAL per region is not used because it might result in a lot of disk seeks when there are large number of reasons. But how about having as many WALs as the number of HardDrives in the system. I see that the recommended configs for HBase are 4 - 12 hard drives per node. This might kick the writes up a notch.
Would like to know the general opinion on this one? Cheers, Akash A
