Mem0 store
Mem0 Long-Term Memory Store
Async-first implementation of :class:BaseStore that uses the mem0 library
as a managed long-term memory layer. In TAF we treat the graph state as
short-term (ephemeral per run / session) memory and a store implementation as
long-term, durable memory. This module wires Mem0 so that:
astore/asearch/ etc. map to Mem0'sadd,search,get_all,update,delete.- We maintain a generated UUID (framework memory id) separate from the Mem0 internal id.
- Metadata is enriched to retain memory type, category, timestamps and app scoping.
- The public async methods satisfy the :class:
BaseStorecontract (astore,abatch_store,asearch,aget,aupdate,adelete,aforget_memoryandarelease).
Design notes:¶
Mem0 (>= 0.2.x / 2025 spec) still exposes synchronous Python APIs. We off-load
blocking calls to a thread executor to keep the interface awaitable. Where Mem0
does not support an operation directly (e.g. fetch by custom memory id) we
fallback to scanning get_all for the user. For batch insertion we parallelise
Add operations with gather while bounding concurrency (simple semaphore) to
avoid thread explosion.
The store interprets the supplied config mapping passed to every method as:
{"user_id": str | None, "thread_id": str | None, "app_id": str | None}.
thread_id is stored into metadata under agent_id for backward compatibility
with earlier implementations where agent_id served a similar role.
Prerequisite: install mem0.

Mem0Store
¶
Bases: BaseStore
Mem0 implementation of long-term memory.
Primary responsibilities:
* Persist memories (episodic by default) across graph invocations
* Retrieve semantically similar memories to augment state
* Provide CRUD lifecycle aligned with BaseStore async API
Unlike in-memory state, these memories survive process restarts as they are managed by Mem0's configured vector / persistence layer.
