How to Decide What Your AI Agent Should Remember - Wojciech Pluta, Oracle

AI Engineer · Oct 30, 2026 · Engineering Insights

In-memory systems unlock competitive AI advantage where RAG only provides a read path.

“the data layer, in my opinion, is where you gain a competitive advantage, because it belongs to you.”

Oracle's Wojciech Pluta argues that while RAG systems handle retrieval (the read path), agents need an explicit write path — in-memory systems — to persist what they learn across interactions. The central design question he poses is what an agent should decide is worth elevating to a durable record. The framing positions the data layer, not models or infrastructure, as the primary source of competitive differentiation in AI stacks.
