MinIO launched MemKV to curb AI “recompute tax,” pointing to a shift from vector-only RAG to a cache-first knowledge layer for agents.
MinIO’s MemKV targets repeated work by caching expensive artifacts, with MinIO claiming up to 95% better GPU utilization. The pitch: keep GPUs busy by not rebuilding the same context every run.
This architecture note argues production agents fail from context assembly, not search. It reframes RAG as a knowledge layer with retrieval, structure, access control, provenance, memory, and write‑back.
Two threads complete the picture: embedding staleness and versioning quietly degrade retrieval, and a 12‑metric evaluation harness catches agent failures before they ship.
GPU time is wasted rebuilding context; a cache-first layer can turn idle GPUs into throughput.
RAG failures often come from bad context assembly and stale embeddings, not the model.

Baseline vs. MemKV: cache hit rate, GPU utilization, and p95 end-to-end latency on repeated agent flows.

Embedding freshness: version and re-embed a slice of corpus, A/B retrieval precision/recall and error rates.
Legacy codebase integration strategies...
- 01.
Add a memory tier without replacing your store: start with idempotent retrievals, TTLs, and provenance logs.
- 02.
Define a retrieval contract API and wire a minimal evaluation harness (faithfulness, tool success, cost, latency) before broad rollout.
Fresh architecture paradigms...
- 01.
Design a knowledge layer from day one: retrieval, access control, provenance, memory, and write-back as first-class pieces.
- 02.
Set SLOs and budgets in an evaluation harness early; prevent drift and staleness with embedding versioning.
