Why Versioned SQL Beats Vector RAG for Agent Memory Systems

Stop building agent memory systems on top of vector databases. You're setting your team up for failure. Vector RAG looks elegant in s. Pass a query, get back similar chunks, stuff them into context. Done. But when you scale to multiple agents collaborating over time? It collapses. Hard. Here's why: RAG conflates retrieval with reconciliation. It assumes all knowledge is additive. That conflicts don't exist. That agents won't overwrite each other. They do. They will. What you actually need isn't retrieval - it's merge.
