It’s Time to Move on from Two Phase Commit
If you read it closely, this is very similar to RAMP transaction. Both has pretty significant write amplification for storing transaction metadata and multiple versions of each key. By storing txn metadata and multiple versions, it provides many nice attributes like non-blocking, concurrent transactions, etc.<p>The difference between Abadi's proposal and RAMP is that it moves the "second phase" to the worker, which performs the remote read, to figure out the txn decision.<p>I think this proposal should be better compared to RAMP instead of 2pc. And even in RAMP paper, it states that this doesn't solve all the problems. E.g. how would you do the traditional read-modify-writes?
