             Summary: Allow Gremlin-Python to handle asynchronous failure
                 Key: TINKERPOP-1453
             Project: TinkerPop
          Issue Type: Improvement
          Components: driver
    Affects Versions: 3.2.2
         Environment: Titan 1.1
Gremlin 3.2.2
            Reporter: Carlos Cheung

Titan occasionally returns transaction errors for a transaction that was sent a 
few requests back. Since Gremlin-Python assumes a request sent will get only 
its own answer back, this can cause the request-answer to no longer be in sync 
and there is no mechanism to recover. 

It would be nice to have a way for the receiver to check the request-id to see 
if it corresponds to the original request. Additionally there should be a 
rolling transaction log in the case of a server error, so a recovery/try might 
be possible. 

By implementing this, it would be possible to send Gremlin queries 
asynchronously as well.
