So a common way make time-series based graph data is to put the timestamp info in the "edge" between "nodes."
For example, this is quite easy to do with neo4j and its easy to make time-series based queries via cyphersql (ie, return all nodes that have edges with timestamp between a min and max. )
How can I do the same thing with dgraph ?
As far as I can tell, an "edge" is a predicate in dgraph, and a "node" is a schema in dgraph.
So, this means i should put a timestamp in the predicate (?)
