- facetube 8y agoFrom the point of view of a single cluster or node (ignoring replication for a moment), it just doesn't have any strong notion of transactions. There's no write-ahead log, no rollback, and no situation where you'd be able to operate in a mode equivalent to something like `SERIALIZABLE` on a relational database.
- HumanDrivenDev 8y agooh right, I understand what you mean now. I guess most people should know that going in. Are their good master-master systems out there with local transactions?
- facetube 8y agoThe claim from daimenkatz was that transactions and MVCC are supported internally, but not externally. It's unclear to me if any of this is accurate. Here's the information that was offered: https://github.com/couchbaselabs/couchstore/wiki/Format https://github.com/couchbaselabs/couchstore/wiki/Format. Let me know if you see MVCC or transactional behavior in there.
