NotImplementedError when calling toGremlin in FoldedContextField

See original GitHub issue

Hey guys!

First of all, thanks a lot for this awesome work. I was testing the compiler in combination with Gremlin. The following GraphQL is mentioned in your Readme, but causes a NotImplementedError when trying to generate a Gremlin statement out of it:

Animal {
        name @output(out_name: "name")
        out_Animal_ParentOf @fold {
            _x_count @filter(op_name: ">=", value: ["$min_children"])
                    @output(out_name: "number_of_children")
            name @filter(op_name: "has_substring", value: ["$substr"])
                 @output(out_name: "child_names")
        }
    }

Is it a bug or is it just not implemented.

Many thanks!

Hi! We started to implement our own Java based compiler for Datastax DSE Graph. I will let you know when I touch this point and create a PR.

Again many thanks! The project is really awesome!

Oh, interesting! How does filtering work, then? Assuming you’ve figured out the syntax DSE Graph uses, it shouldn’t be too difficult to add a customized Gremlin backend that can emit the correct Gremlin syntax for DSE Graph as well – I am happy to guide you in that process, if you are interested.
