Apache Airflow Implementation in Durham
Implementing Airflow for Durham 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

Working in Durham
North East
Durham's economy is dominated by its university and cathedral, so the commercial base is small and much of the local demand comes from spinouts and suppliers attached to the institutions rather than from independent industry.
Research spinout software and visitor systems, usually on institutional procurement timelines rather than commercial ones.

Apache Airflow Implementation in Durham — 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 County Durham?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout North East, including Durham and the surrounding County Durham area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Durham businesses do you usually work with?
- Research spinout software and visitor systems, usually on institutional procurement timelines rather than commercial ones. Beyond that we work across Higher Education, Tourism & Heritage, Public Sector, Retail and Research.
- Do you cover the areas around Durham?
- Yes — we work throughout North East, including Newcastle, Sunderland, York. Durham is an urban area of roughly 70,000+, and we take on work across the wider County Durham region rather than the city boundary alone.
