DataOps

WHAT IT IS DataOps is the operating model for moving data through its lifecycle — ingestion, transformation, storage and delivery — with the same engineering discipline that /devops brought to application delivery. It treats a pipeline as a production system: versioned, tested, monitored, and owned by someone who is paged when it fails. **Not this:** DataOps is not AnalyticsOps: it owns the pipeline that delivers the data, not the metric definitions and dashboards built on top of it. WHY IT EXISTS Data pipelines fail quietly. An application outage announces itself; a pipeline that silently drops ten percent of rows produces a dashboard that is merely wrong, and the business acts on it for a week before anyone notices. The cost is not downtime — it is decisions made on data nobody validated. DataOps exists because the failure mode is silence, and silence has to be engineered against deliberately. WHEN TO USE IT Adopt it when more than one team depends on data someone else produces, when a schema change upstream has already broken something downstream, or when the answer to "is this table current?" involves asking a person. A single analyst querying a single database does not need this. Three teams and a warehouse do. WHO OWNS IT Data engineering owns the pipelines and their reliability. The producing team owns the contract for what it emits — this is the ownership boundary teams most often leave undefined, and the one that causes the most breakage. A data platform team, where one exists, owns the shared infrastructure and the standards. Analytics consumers own their use of the output, not its correctness. WHAT GOOD LOOKS LIKE Every dataset has a named owner and a stated freshness expectation, and something automatically checks that expectation rather than waiting for a complaint. Schema changes go through a contract with consumers instead of arriving as a surprise. Pipeline code is reviewed, tested and deployed like application code. Failures page the owner with enough context to act, and backfills are a documented procedure rather than an improvisation. Data quality tests run on every load, and a failed test blocks publication rather than annotating it. HOW TO IMPLEMENT Start by inventorying the pipelines that already exist, including the ones running on someone's laptop — those are the ones that will surprise you. Give each a written owner and freshness expectation. Add automated freshness and row-count checks next, because they catch the majority of silent failures for very little effort. Then introduce schema contracts at the boundaries where teams hand data to each other. Move pipeline definitions into version control with code review before you invest in sophisticated orchestration; orchestration on top of unreviewed logic just fails faster. Adopt the same incident habits as /incidentops — an on-call owner, a severity rubric, a written retrospective. HOW TO ASSESS YOURSELF Ask what happens when an upstream schema changes: who finds out, and how long does it take? Ask how many pipelines have an owner who knows they own them. Ask whether a failed data quality test stops the data from being published, or merely records that it was bad. Take the structured self-assessment at /assess to get a scored picture, then use /roadmaps to sequence the gaps. The operating checklists at /checklists cover the recurring pipeline reviews.
