Write, Change, Recall, Forget: MongoDB's Pete Johnson on How Retrieval Drives Agent Performance
Article image or reusable cover for The Cognitive Revolution
In an episode of The Cognitive Revolution, Pete Johnson from MongoDB discusses how databases work and why memory systems for AI agents remain an unsolved problem.
Johnson explains that traditional SQL databases were built when storage was expensive, so they fragmented data across many linked tables to save space. The conversation also covers how modern databases like MongoDB work differently, and the major technical challenge of getting AI agents to remember and retrieve the right information when they need it.
