             Summary: Make borrowing a connection from a pool async
                 Key: TINKERPOP-2839
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-2839
             Project: TinkerPop
          Issue Type: Improvement
          Components: driver
    Affects Versions: 3.5.4
            Reporter: Stephen Mallette


TINKERPOP-2813 stopped fast {{NoHostAvaialbleException}} errors but the change made it more evident that {{submitAsync()}} was never as async as it should have been. Since {{ConnectionPool.borrowConnection()}} was synchronous you could still have a block, but it was then quickly hidden for future requests by the fast NHA that would follow a {{TimeoutException}} from that wait. It seems like borrowing a connection would have to be async if we wanted {{submitAsync()}} to be truly behave as its name implies.
