(An earlier post seems not to have gone through. My apologies in the eventual case of a duplicate.)
I'm thinking of using Riak to replace a large Oracle system, and I'm trying to understand its guarantees. I have a few introductory questions; this is the third of three. I would like to do two updates atomically, but of course I cannot. I imagine I could construct my own redo log, and perform a sequence of operations something like: write redo log entry (timestamp, A's update, B's update) to redo log update A update B delete redo log entry from redo log Asynchronously, I could read dangling entries from the redo log and repeat them, deleting them upon success. (Let's imagine for simplicity that the updates are idempotent and commutative.) This seems doable, but it's not pretty. Is this the best I can do? Or should I think about the problem differently? (BTW, I believe that secondary indexes won't help me.)
