interesting idea using multiple labels to indicate the trail / session. I wonder how that would scale? I saw this thread that talked about the pros/cons of using route labels vs intermediate nodes
It just seems the name of the label is a 'key' whereas your trails are more like the 'value', so using labels in the way you're proposing seems like it would run out of steam, to say nothing about how indexes work?
For my project, with cypher I'm having trouble just getting back info on arbitrary sized paths with a different number of nodes in-between, as per:
If you're going with a node-first approach I'd be interested to see your queries to read that stuff back (and what driver you're using).
