Re: Gremlin Query to return count for nodes and edges

Graham Wallis <graham_wallis@...>
 

Good query from @hadoopmarc and I like @cmilowka's suggestion, although I needed to modify it very slightly as follows:

g.V().hasLabel('A').union( __.count(), __.outE().count(), __.outE().inV().count() )

That has to be the shortest and neatest solution. Certainly far better than my rather basic effort below, which surely gets the prize for the longest solution :-)

g.V().hasLabel('A').aggregate('a').outE().aggregate('e').inV().aggregate('b').select('a').dedup().as('as').select('e').dedup().as('es').select('b').dedup().as('bs').select('as','es','bs').by(unfold().count())


Best regards,
