What you wanted to do

In dgraph-ratel the “expand” button is extremely helpful. I generally start off with a simple query and expand from there. One issue I have is that when I perform a query (especially recursive queries) the fanout can be quite large. I’d like to have a “remove” button that lets me click a node and remove it, and subsequently removes all nodes that are no longer reachable from a forward edge (that were previously reachable).

Essentially, given a graph with:
A, B, D, C


If I click “remove” on “B” it will also remove “D” as it is no longer reachable.

What you actually did

Right now I don’t have a good solution to this. Huge fanout can really bog my browser down and I end up having to create smaller queries and manually expand out with the “expand” button.

Why that wasn’t great, with examples

I model process trees in dgraph. Fanout is generally small, but once in a while a process will have massive fanout (like a background process). I’d like to be able to selectively prune out those processes without having to make overly complex queries.

Any external references to support your case

Would you like to delete these nodes from Dgraph? Or only from the graph visualization in Ratel?

insanitybit commented :

Just from the visualization - similar to how the “expand” just modifies the visualization.

Thanks for clarifying. I’ll move this issue over to the Ratel repo.
