Re: Aggregating edges based on the source & target vertex attributes
Thank you Marc. As you mentioned I might be able to execute the above mentioned aggregation query faster if I use other tools/datastore. But, I was exploring JanusGraph primarily for OLAP use-cases.

RDF Import into JanusGraph
Hi,
I want to know whether we can import RDF(Any format like Turtle or RDF/JSON) into Janusgraph or not.
If yes then what are the steps to do that.
Any help will highly be appreciated.
Thanks.
