Add workflow analytics world APIs by karthikscale3 · Pull Request #2234 · vercel/workflow

karthikscale3 · 2026-06-03T17:41:48Z

What changed

Adds a new metadata-only world.analytics.* namespace for workflow observability reads.

Adds analytics schemas and types in @workflow/world
Adds optional analytics?: Analytics to the World interface
Adds createAnalytics() in @workflow/world-vercel
Wires createVercelWorld() to expose world.analytics
Adds a changeset for @workflow/world and @workflow/world-vercel

Why

This gives observability surfaces an explicit ClickHouse-backed read surface without changing the existing runtime storage APIs. Payloads, RemoteRef resolution, inputs, outputs, and error hydration remain on the canonical DynamoDB-backed APIs.

Validation

pnpm --filter @workflow/world exec tsc --noEmit --pretty false
pnpm --filter @workflow/world-vercel exec tsc --noEmit --pretty false
pnpm exec biome check packages/world/src/analytics.ts packages/world/src/interfaces.ts packages/world/src/index.ts packages/world-vercel/src/analytics.ts packages/world-vercel/src/index.ts
