Re: Gremlin Query to return count for nodes and edges
Vinayak Bali
Hi All,
The query shared by HadoopMarc works. The query, I executed returns 752650 nodes and 297302 edges as a count. The time taken is around 1min. Is there any way to optimize it further ???
Thank You, Marc, and all others for your help.
Thanks & Regards,
Vinayak

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,
