Serverless Request Budget

A serverless publishing workflow may fail to publish an approved article if the queue cleanup process consumes the requests needed to read the publication.

Quick solution: To prevent this issue, reserve the publication reads before performing background queue cleanup by checking remaining execution limits.

Implemented Repair

The implemented repair checks the existing ready queue and remaining request allowance before fresh-candidate lookup or cleanup. If the publication reserve plus the bounded candidate write cannot fit, it records the candidate as deferred and proceeds to inspect the ready article. When managing multi-step editorial workflows, you can also review strategies like Deferring Publication After A Budget Safe to ensure predictable execution limits.

Evidence and Limits

The implemented repair has been tested with local test suites, typechecks, coverage thresholds, and Wrangler deployment dry runs. A regression test reproduces a revision consuming high requests with reserved overhead and verifies candidate preparation is skipped while the older ready draft is still read.

Why This is Not a Duplicate

This solution concerns allocating scarce requests between queue maintenance and existing publication discovery, rather than generic provider retries or unrelated timeout adjustments.

Verification Checklist

• Check the request allowance before performing queue cleanup
• Reserve publication reads to prevent request budget starvation
• Verify that the implemented repair does not disable the scheduler or weaken content checks
