Seeking nosql advice. I'd like a system that allowed for standing queries instead of synchronous queries.
With mongo, if you want to know if something has changed, you send in a query.
I'd like to have a client subscribed to the db. Essentially, it's saying, "Whenever you get a dictionary that matches this query, send it through to me." It would hold this subscription over a standing socket connection.
Does anyone know of a system like this?
