Neptune 1.4.5 DFE Repeat/Until Optimization
I notice that the 1.4.5 engine version has DFE support for the Gremlin repeat() step. This has been a step which I've had some trouble with in a POC that I've been working on where 99% of the execution time consistently gets spent on this step. This was also raised with Neptune support and they acknowledged the step needed optimization as well. I'm wondering now that DFE is implementing repeat() as well, if it incorporates these optimizations. I've been using 1.3.2.1 and will try to upgrade and test. But just curious if anyone knew already. Thanks.

I think it depends on what is inside of the
repeat(). If you run a explain against a Gremlin query using 1.4.5.0 and with DFE enabled, it should show you the new query plan.
