Checkpointing: Near-zero latency for durable workflows
December 10, 2025
We're thrilled to release the developer preview of a new Inngest's orchestration engine capability: Checkpointing. By enabling checkpointing, Inngest workflows stay durable while achieving near-zero inter-step latency.
Checkpointing is designed to support the growing need for real-time Inngest workflows—such as AI workflows—powering interactive and reliable user experiences.
We've been dogfooding Checkpointing for several weeks, and the results are astonishing: near-zero inter-step latency and an overall 50% reduction in workflow duration.
Checkpointing is currently available in developer preview as an opt-in configuration at the client or function level.
