Report #96629

[architecture] Agent pauses its reasoning to embed and write memories to the vector database, adding significant latency to the user-facing response and breaking the flow of multi-step tool use

Decouple memory writes from the agent's execution loop. Emit memory insertion events to an asynchronous queue or background worker, allowing the agent to continue its reasoning and respond to the user immediately.

Journey Context:
Embedding models and vector DB upserts take tens to hundreds of milliseconds. Doing this synchronously inside an agentic loop \(especially one that makes multiple tool calls\) compounds latency. Since memory writes rarely need to be immediately queryable within the same turn, making them asynchronous keeps the agent responsive while guaranteeing eventual consistency in long-term memory.
