zed --explain does indeed highlight recursions: https://authzed.com/docs/spicedb/modeling/recursion-and-max-depth#what-do-i-do-about-a-max-depth-error-on-checkpermission
@josephschorr, sure, but that doesn't solve the problem statement. If a lookup-resources request results in a cycle, it can be challenging to identify where in the data the cycle is occurring. There is no equivalent of --explain for lookup-resources.
Problem Statement
Sometimes there may be cyclic data accidentally stored into SpiceDB and right now it's kind of hard to identify where in the data there is a cycle. It's only really realized with calls like lookup-resources as that will do a full traversal and not short circuit like with check permission.
Solution Brainstorm
It may be useful to include in the
--explain
feature some kind of highlighting if a particular node in the graph was traversed more than once (or however many time it was traversed), so that the user can more quickly identify a cyclic data problem in their DB.
