Hello,
We use the term "union()" to describe the n-furcation of a traverser across
n-(nested)traversals. The union()'ing happens at the end when the
n-parallel-streams get merged/unioned back to one. Given that Gremlin is read
left-to-right, it feels more natural (for me) to say "split()" as that is what
is happening on the left of the union(). Yes, like TinkerPop2.
g.V.union(out('knows'), in('created')).name
VS.
g.V.split(out('knows'), in('created')).name
The top you are interpreting, union the results of the two internal traversals.
Where the assumption is split at the beginning.
The bottom you are interpreting, split the traverser across the two internal
traversals. Where the assumption is union at the end.
For me the latter gives the more "particle" perspective to Gremlin, while the
former gives the more algebraic perspective.
Note that this would be a straightforward deprecation as its a rename with no
semantic alteration.
Thoughts?,
Marko.
