How do I ensure long-term persistence doesn't reset on restart?

For production environments, use the PostgresStore instead of InMemoryStore. InMemoryStore is lost when the application process restarts, while PostgresStore keeps data in a permanent database.

What is the difference between StateBackend and StoreBackend?

StateBackend provides ephemeral storage that exists only within a single thread and is lost once the thread ends. StoreBackend provides long-term persistence that allows data to be shared and accessed across different threads and sessions.

Can I route different file paths to different storage engines?

Yes, using the CompositeBackend you can define routing rules. For example, you can route '/tmp/' to an ephemeral StateBackend while routing '/memories/' to a persistent StoreBackend.

Is FilesystemBackend safe for production web servers?

No, FilesystemBackend is designed primarily for local development and CLI tools. For web servers, you should use StateBackend or a sandboxed environment to prevent unauthorized access to the host's filesystem.

Data Science & ML

Manages short-term and long-term memory for AI agents through pluggable storage backends and secure filesystem access.

Deep Agents Memory provides a comprehensive framework for managing state and persistence within AI agent workflows. It offers several specialized backends—including StateBackend for ephemeral thread-level memory, StoreBackend for cross-session persistence, and FilesystemBackend for direct disk access. By utilizing a CompositeBackend, developers can implement sophisticated routing logic to ensure sensitive data remains ephemeral while core memories persist across multiple threads. This skill is essential for building complex agents that need to retain context, follow long-running instructions, or interact with local codebases securely.
