This is very sad to hear this looked like a real product.

Quite off-topic but has anyone managed to implement something similar to Changefeeds in MongoDB? RethinkDB sends both old data and new data and watching the oplog sounds like a bad idea.

That's what literally everyone does for changes on mongo, from Meteor to Firebase. There isn't another way

Honestly interested: how do you know Firebase works that way and do you have any links to more info about how Firebase works?

I talked with them a while back. It's possible now that they're at Google they've changed their back end to work without mongo or whatever, but at least pre-google, that's my understanding.

no, notifications have never worked through oplog watching. It's a custom application layer infront of persistence that sends the mutation transition to registered parties. The oplog is too coarse grained.

Ah, ok, I must have misremembered. Apologies
