    Description

      Currently, change stream requires 1 connection for each watcher to be notified through MongoDB driver.

      In a fairly medium complex reactive application or in micro service architecture having hundreds of watchers is common but since MongoDB driver consumes 1 exclusive DB connection for each watcher registered it becomes a scaling problem.

      A more reasonable design would allow registering/multiplexing multiple watchers over single DB connection.
