Hi Mark, I don't really know what to make of that thread and I wouldn't pretend to understand everything thats being talked about here or there....so i'm jst thinking out loud.
I believe I might have mis-spoken by calling it a driver..... its really a LC external that acts as a driver. If you go to this page ..... the specs say that it all happens through an tcp/ip connection where you make a connection, serialize the query and send it .... the db driver port receives queries, and streams data from the db via the TCP/IP back to "subscribed" client. So it doesn't really need to have anything to do with the current revdatabase functions....which the posts seem to be talking about. I'm not asking for a rewrite of db layer. It would be more perform ant to build this as an external and closer to the engine...as far as I know anyways..... unless thats completely wrong. Here is the link again....... https://www.rethinkdb.com/docs/writing-drivers/ Thanks for making me aware of the past efforts with RethinkDB.
