DATA OPS

Source Feed Arrival Deadline Watchdog: Escalate the Late Upstream

Watches for an expected source file to land in cloud storage by its daily deadline; if it's missing, it escalates to the data team and the upstream vendor, then logs the SLA miss.

What it does

Guards the front of the pipeline rather than the warehouse end. It confirms a vendor or partner dropped the expected file into storage by the contractual deadline. A no-show is caught and escalated to both your team and the upstream provider before downstream loads even start.

When to use it

Use it when your pipeline depends on an external feed that must arrive by a set time — a daily partner export, a finance extract, a third-party data drop — and a late or missing file should trip an alert, not a silent empty load.

How it works

  1. 1A schedule fires shortly after the feed's contractual deadline.
  2. 2List the expected prefix in the S3 bucket and check for today's file by name and minimum size.
  3. 3Logic decides arrived-on-time, late, or missing.
  4. 4If missing past the grace deadline, open a PagerDuty incident for the data on-call.
  5. 5Email the upstream vendor contact with the expected file and deadline missed.
  6. 6Append the arrival outcome (on-time, late, missing) to the feed SLA log.
