Two Roads to Durable Agents: Replay vs. Snapshot — Eric Allam, CEO, Trigger.dev
This talk explores the fundamental shift required for AI agents in backend infrastructure, moving from stateless to stateful compute. It proposes two primary methods for achieving durable agents: replay and snapshotting. Replay, an evolution of traditional workflow engines, logs every interaction but can become unwieldy with complex agents. Snapshotting, a newer approach, preserves the entire execution state of a machine, offering a more robust solution for long-running, complex agent sessions.
