Right now I am able to generate a query to create as many vertices and edges as I want. e.g. g.V(). addV('vert1').as('a'). addV('vert2').as('b'). addE('has').from('a').to('b') ^^^^^^^^^^^^^ This w...

Background: I'm trying to implement a time-series versioned DB using this approach, using gremlin (tinkerpop v3). I want to get the latest state node (in red) for a given identity node (in blue)...
