Agent memory database
Read the category page before comparing vendors. It defines the retrieval signals an agent memory store needs and the tradeoff between a service and an embedded engine.
Compare the memory boundary, not just the nearest-neighbor score.
These pages compare MongrelDB with agent-memory frameworks and embedded vector stores on the questions that decide production fit: who owns storage, which retrieval signals are native, how writes stay consistent, and what happens when the workload grows past a demo.
Rule of thumb: choose the narrower tool when its model already matches the job. Choose MongrelDB when semantic retrieval has to share one engine with exact text, metadata, recency, deduplication, SQL, transactions, and encrypted storage.
