Re: Official support for FoundationDB?

Jason Plurad <plu...@...>

+1. I support having a janusgraph-foundationdb repository under the main JanusGraph org on GitHub. There is precedent for this with janusgraph-docker, language-specific client bindings (janusgraph-dotnet and janusgraph-python), and janusgraph-ambari.

It comes down to whether there is a consensus desire to collaborate together instead of having separate forks. There would be some work from those fork authors to agree on how to merge those forks into the one that will serve as the initial repo. There would be more restrictions on getting code committed since the project would be expected to have a code review and approval process in place, like the other JanusGraph repos. Keep in mind that having a repo under the JanusGraph org doesn't mean that it needs to be production worthy from the start.

Thanks to both of you for getting the ball rolling here with FoundationDB. Happy to hear more feedback/discussion from the community.

I agree we would have to clearly state all limitations the adapter has so everyone is aware of them. 

Would love to hear additional feedback from the community on the topic of making this adapter official.

Hi Christopher,
thanks for offering your support!

I did indeed put a lot of effort into my fork (rngcntr), but I worked alone and rewrote a significant amount of code so it definitely lacks an in-depth review. Other than that, most of what I did was stress testing and finding bugs that need to be fixed. There are stil some open issues but all in all I'm quite happy with the current state of the storage adapter.

What still worries me is the effects of the transaction time limit of FDB. Officially supporting FDB as a storage backend would currently leave the user in charge of handling these problems. Retrying can not solve all problems as some queries will never make it through the 5s limit, even when tried over and over again. This results in the FDB adapter only supporting a subset of all possible queries and this should be stated clearly in case it is officially released.
