  • I included a self-contained, minimal example that demonstrates the issue INCLUDING all the relevant imports. The code run AS IS to reproduce the issue.

Example Code

No code Required.

Error Message and Stack Trace (if applicable)

Description

I've implemented store to save the long term memory and I'm running langgraph server locally.

In my langgraph studio, under the memory I could see all the namespaces I've created and if I want to delete a namespace there is no option for me to.

I think that data is getting store in memory right? I dont know how to remove them, I see there is an option to remove the keys and values, but I want to delete the namespace. Because all the unnecessary namespaces that I've used for different projects are still left there and I want to delete them and the files inside them.

To delete a namespace, you delete all the items in that namespace right now

Going to close as stale, since it's already possible to delete items. Namespaces only exist as a function of the items that exist in memory.
