Pairing Cron Triggers with Worker Queues for Long-Running Healthtech Reports

A developer guide describes using a nightly cron job to publish a single idempotent reconciliation request, rather than running long reports directly inside the scheduler. A worker queue consumer then handles the slow report generation, retries, completion tracking, and email delivery. The article explains that standard queues are at-least-once, so consumers must be idempotent, and recommends keeping trigger messages small with a deterministic job key. It notes cron's 900-second execution limit and that missed triggers are not backfilled, making deliberate replay procedures necessary. The piece also includes a TypeScript snippet for discovering a queue capability schema before implementing the publish call.
