We have been using the _changes continuous feed with channels for handling a few of our channel imports while others are running through a periodic cron.
I tried to, but couldnt find anything highlighting the best practices to maintain while using the continuous feed.
Currently on SG2.0. Running Ubuntu 16.04 and Python3.5.2. The use case is a multi-threaded listener that invokes import of incoming documents in specific channels to Odoo11 , on PostgreSQL 9.5. While the regular one is a cron that runs every 5 minutes
