Builds and operates data pipelines — ingestion, transformation, orchestration, quality testing, and reliability of data delivery. Use this to design or debug a pipeline, decide batch versus streaming, add data quality checks, handle late or duplicate data, or work out why a dashboard's numbers changed without anyone changing the dashboard.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Data engineering Pipelines are production systems whose failures are quiet. A broken service pages someone; a broken pipeline produces plausible numbers that people act on for a week. This is movement and transformation. Schema and semantics belong to `data-analytics:data-modeling`, policy and stewardship to `data-analytics:data-governance`. ## Land raw, transform downstream Keep an immutable copy of source data exactly as received. Transformation logic will be wrong at some point, and raw data is what lets you reprocess rather than re-request from a source that may no longer have it. Business logic belongs downstream where it is visible and testable, not buried in ingestion. The exception is transformation required for privacy — minimization, pseudonymization, dropping fields you have no basis to hold — which belongs at ingest precisely because raw storage is what the obligation attaches to. See `legal-risk:privacy-and-data-protection`. ## Idempotence is the property that matters Every pipeline will be re-run: after a failure, after a fix, after a late-arriving correction. A re-run that double-counts is worse than a failure, because it produces a wrong answer silently. …

How to install
mdr add cbrock84/headcount/data-engineering@sha256:65d5030a6913e94bThe line at the top of this page pins the label git:20260916.e72e404, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
