Compatibility with Deep Agents

[amotl]

About

The LangChain family spawned another package, deepagents.

Details

With that package, you can use PostgreSQL as long-term memory. What about CrateDB?

from langgraph.store.postgres import PostgresStore
import os

store = PostgresStore(connection_string=os.environ["DATABASE_URL"])
agent = create_deep_agent(
    store=store,
    backend=lambda rt: CompositeBackend(
        default=StateBackend(rt),
        routes={"/memories/": StoreBackend(rt)}
    )
)
