connection pool
you can now submit queries through a native library connection pool. This pool creates a set of connections and queues work submitting items such that all connections are busy providing work exists. A keep alive is sent periodically to check connection integrity and idle connections beyond a threshold are closed and re-created when queries submitted at a later point in time. Queries can be cancelled and paused / resumed regardless of where they are in the work lifecycle
examples can be seen here and here
