You have resilient reads, idempotent writes, and retry logic. This week you assemble them into pipelines you can validate before starting, track step-by-step while running, and resume from the last good step if something fails.
So the pipeline knows which steps ran? Even across crashes?
That is the checkpoint pattern. Each step records [name, success]. On restart you read the checkpoint, skip the completed steps, and pick up from where you stopped. Combined with idempotency, re-running is always safe.
And the capstone on Day 28 ties all four weeks into one function?
Config validation, three idempotent writes, retry around each, checkpoints at every step, one final report. Every pattern from the whole track assembled into one production-shaped pipeline.
[name, success]Goal: Pipelines you can run, pause, and resume.
