The linked blog post at the top of this article - https://muratbuffalo.blogspot.com/2023/01/is-scalable-oltp-in-cloud-solved.html https://muratbuffalo.blogspot.com/2023/01/is-scalable-oltp-i... - provides graphics that give extremely useful context. And here's the repo for the paper that discusses: https://github.com/DataManagementLab/ScaleStore https://github.com/DataManagementLab/ScaleStore The idea that one of many writer-compute-nodes can literally reach into a memory buffer that is shared across machines, atomically flip some lock bits and propagate some cache-coherence messages, and use that to build a multi-writer distributed database without needing to partition (and where any writer-compute-node can handle any message, so you can just round-robin a firehose of messages at them)... and that there's a chance (though not yet implemented) that one could implement ACID on top of this? It's absolute madness, and wildly exciting.
