Yeah - what i was saying was that you now have the step available to do this:

{code}
g.V().hasLabel('person').
  project('name','age').
    by('name').
    by('age').
  write('somefile.json')
{code}

yes?

>             Project: TinkerPop
>          Issue Type: Improvement
>          Components: io, process
>    Affects Versions: 3.2.5
>            Reporter: Daniel Kuppitz
>            Assignee: Daniel Kuppitz
>            Priority: Major

> Provide a way to save (tabular) results to text files, just like Spark's {{saveAsTextFile}}.
> I'm not sure about the best way to do it. 3 options come to my mind:
> # a new step.
> # a {{VertexProgram}}
> # a configuration option
> Things to consider / open questions:
> * Is it sufficient to simply {{toString()}} all values or should we allow formatters / format stings?
> * [~jlewandowski] pointed out that it would be nice to have support for the [parquet file format|https://parquet.apache.org/]. I guess now we're already talking about support for different {{FileOutputFormats}} and not just formatters.
> * Is that only relevant for OLAP?
> * Can we support arbitrary file systems?
