Hi All, Currently, it is difficult for a user to tell if upgrading their graph database to a newer version will cause their application to break. We don't know which versions of the driver will work with which versions of TinkerGraph running in the Gremlin Server. This question gets even more complicated when you need to consider other providers. This sort of driver and server compatibility testing is missing from Apache TinkerPop.
To solve this problem, I've been working on a system that will allow testing for these scenarios. A very early version of it can be seen here ( https://github.com/apache/tinkerpop/commit/c1e1bfdbce09cab08d08a53a53886a2d645f4274). Right now, it is only capable of running the non-Java GLVs feature tests against different versions of TinkerGraph. However, the vision for this system in the future would be for it to be able to run a customizable set of feature tests, on any GLV, against any provider. I'm curious if there are any providers that have experienced similar questions from their users about which versions of the GLVs they can use against different versions of their server. Thanks, Ken
