Hi! Our company is starting a new project, and I suggested trying SpiceDB as a great access control solution. We found an article that says we can also use it to find relations between entities without storing that information in a classic relational database like PostgreSQL. https://authzed.com/blog/writing-relationships-to-spicedb The question is: for example, we have two definitions such as "resource" and "user." Is it possible somehow to find all resources to which a user is related? Usually i see what "user" is just blank definition and in resource we have several relations (for example by roles: "administrator", "viewer", etc). Have no idea how to make such request by user id

Hi, welcome 👋 SpiceDB defines relations and permissions. Permissions are computed out of set operations over relations. If you want to read relations a user has with a resource, yes you can do that with

ReadRelationships

. If however you want to answer the question tell me all the resources the user has

view

access to, then that's is done with

LookupResources

oh thanks then one more thing - is it possible to ask "tell me all the resources the user has any relation to"?

I'd like to stress that "relation" is different than "permission". Relation would be like an edge in a graph, which is what you construct when you store things in SpiceDB

Thank you so much, you just solved all our main concerns about using spicedb 🙂 Thanks!
