Report #86456

[architecture] Agent pauses to embed and save a memory to the vector store during a multi-step task, causing high latency and poor user experience

Decouple memory ingestion. Write raw memories to a fast, ephemeral buffer \(like Redis or local state\) synchronously, and process/embed them into the long-term vector store asynchronously via a background worker.

Journey Context:
Vector DB upserts and embedding generation are slow \(often 100ms\+\). If an agent must save a memory before proceeding to the next tool call, the user waits. By using an ephemeral buffer, the agent acknowledges the save instantly and continues. The background worker handles deduplication, embedding, and vector upsert. The tradeoff is that memories aren't instantly queryable in the vector DB \(eventual consistency\), but for agent episodic memory, a few seconds delay is acceptable.
