I'm creating arount 1000 streams and sinks for them, so cassandra cluster would be saturated with openning connections. Cassandra session could manage several connections via one session. Could you confirm that this isn't an issue with the implementation? --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
