Strong vibes from RethinkDB. I hope SurrealDB will have a different fate, I'm a big big fan of live queries and change feeds and don't like most existing implementations.
This immediately sprung into my mind. Already got bitten by RethinkDB (trusted it too much to do some logic, rewrite was painful), so I’d rather have reasonably easily replaceable third-party components than depend on something unique, especially without any guarantees.
Can you give a quick elaboration on what you mean about the fate of RethinkDB? I'm not familiar with it.
