Observational Memory
### TL;DR
Observational Memory is Mastra's innovative memory system designed for long-context agentic memory. It utilizes two background agents—an Observer and a Reflector—to monitor agent conversations and maintain a dense observation log, effectively replacing raw message history as it grows. This approach enhances performance by compressing context and ensuring a stable context window.
