Let's consider a simple scenario under normal riak. The key concept here is to realize that riak's vnodes are completely independent, and that failure and partition ownership changes are handled through handoff alone. Let's say we have an 8-partition ring with 3 riak nodes: n1 owns partitions 1,4,7 n2 owns partitions 2,5,8 n3 owns partitions 3,6 ie: Ring = (0/n1, 1/n2, 2/n3, 3/n1, 4/n2, 5/n3, 6/n1, 7/n2, 8/n3) Each node runs an independent vnode for each partition it owns, and each vnode will setup it's own bitcask:
Do the redundant writes still go to different physical nodes or just vnodes that might be on the same host and fail at the same time?
