Daniel Kuppitz commented on TINKERPOP-1298:
-------------------------------------------
Without TINKERPOP-1280 traversals have to have a {{select()}} step (or any
other step that has a {{LABELED_PATH}} requirement). So instead of
{code}
g.V().as("a").out().as("b").out().as("c").
program(BulkExportVertexProgram.build().
keys("a","b","c").create(graph))
{code}
... you have to do:
{code}
g.V().as("a").out().as("b").out().as("c").
select("a","b","c").
program(BulkExportVertexProgram.build().
keys("a","b","c").create(graph))
{code}

> Issue Type: Improvement
> Components: io, process
> Reporter: Daniel Kuppitz

> 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?
