Is there a MongoDBStore equivalent of PostgresStore for cross persistence in langgraph?

[pritamsinha2304]

Hi, I have a general question. I am implementing a store functionality in my langgraph for cross-persistence. I refer to this doc How to add cross-thread persistence to your graph. In this, they have used InMemoryStore() for persistence across threads. But is there something similar for MongoDB, like MongoDBStore(), something like that? There is PostgresStore.

I found this langchain-mongodb repo, from which I have implemented the MongoDBSaver checkpointing in my langgraph. But do not see a Store functionality in that?

Any insight on this? Thanks
