Apache Airflow Implementation in Chester
Implementing Airflow for Chester organisations, where treating it as a scheduler with a web interface leads directly to the first surprise. Pipelines have a notion of the period they are processing, and deploying one with a start date in the past can trigger a great many historical runs at once — which is a feature and rarely what anybody intended.
Why this comes up
The problem
A new pipeline was deployed with a start date last year, and it immediately began executing hundreds of backfill runs.
What you get
What we deliver
- Catchup behaviour set explicitly per pipeline rather than left at the default
- Tasks written to be idempotent, since reruns are normal rather than exceptional
- Pipelines parameterised by the period they process, not by the current date
- Concurrency limits set so one heavy pipeline cannot exhaust the workers
- Failure alerting configured to reach a person rather than sitting in the interface
- Dependencies expressed in the pipeline rather than in scheduled start times

Apache Airflow Implementation in Chester — common questions
- What is catchup and why does it surprise people?
- It runs every interval between the start date and now. That is exactly right for a pipeline meant to process history and alarming when someone sets a start date casually — it should be a deliberate setting rather than something discovered on deployment.
- Why does idempotency matter so much?
- Because tasks get rerun — after failures, during backfills, when someone clears a run. A task that appends rather than replaces produces duplicated data on the second run, and that duplication is frequently found much later in a figure that looks slightly high.
- Should tasks use today's date?
- No — they should use the interval being processed. A task querying for today works correctly on the day and produces wrong results in every backfill, which makes historical reruns unusable exactly when you need them most.
- How should dependencies be handled?
- In the pipeline definition rather than by scheduling one job an hour after another. Time-based sequencing works until something runs long, at which point the second job processes incomplete data — and the failure is silent because both jobs succeeded.
- Do you work with businesses across Cheshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout North West, including Chester and the surrounding Cheshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Chester businesses do you usually work with?
- Compliance-heavy systems for financial services firms, and cross-border trading setups for businesses working into Wales. Beyond that we work across Financial Services, Tourism & Heritage, Retail, Professional Services and Agriculture.
- Do you cover the areas around Chester?
- Yes — we work throughout North West, including Liverpool, Manchester, Wrexham. Chester is an urban area of roughly 120,000+, and we take on work across the wider Cheshire region rather than the city boundary alone.
