Interesting - we were just discussing options on the dev mailing list for 
better allowing client-side retry in the event of Titan exceptions

>                 Key: TINKERPOP-1453
>                 URL: https://issues.apache.org/jira/browse/TINKERPOP-1453
>             Project: TinkerPop
>          Issue Type: Improvement
>          Components: driver, language-variant
>    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.
