User isolation in LangGraph memory store

Product Help LangGraph Platform
1

Hi all,

We’re onboarding multiple users and noticed the memory store doesn’t isolate data by default. Even when we manually add user ID namespaces, it still feels like a patch.

Do we need to move to an external solution for proper user isolation, or will LangGraph Cloud provide built-in support for this?

Thanks!

Hi @FocusedCreativity ,

Typically we see users move to an external memory store like Postgres or Mongo that they then enforce this logic in - the InMemory store (which I assume you’re referring to) is best suited for sub-prod apps and so might feel less robust from a data separation perspective

Please let me know if you have any additional questions!
