AI BriefingVercel Workflows Adds Configurable Run State Storage Location
Key point
Vercel Workflows has introduced a feature that lets you pin run state, queue, and output streams to a specific region.
Details
Vercel Workflows can now store each run's State, Queue Dispatch, and Output Streams in a single home region. By default, the home region is the region where the run started, but users can also directly specify a particular region they want.
This feature allows AI agent services to run all loops in a region near the user, reducing latency. For example, an agent for a Sydney user would run, save checkpoints, and produce output in the Sydney region. Additionally, if a regional outage occurs, workflow traffic automatically fails over to the nearest next region.
Key updates:
- Available by updating the Workflow SDK to
[email protected]or later. - You can pin a run to a specific region by passing the
regionoption to thestart()function. (e.g.,{ region: 'sfo1' }) - Existing workflows will automatically get region-pinning support starting from their next run, with no code changes or migration required.
