Large Scale Distributed Consensus Approaches: Concurrent Consistent Decisions

So far we tackled the idea of large compute cluster, and a large storage cluster. I mentioned that the problem with the large storage cluster is that it doesn’t handle consistency within itself. Two concurrent requests can hit two storage nodes and make concurrent operations that aren’t synchronized between themselves. That is usually a good thing, since that is what you want for high throughput system. The less coordination you can get away with, the more you can actually do.
