: Confluent Schema Registry + quality checks.
The book outlines how data contracts act as a formalized interface between data generators and consumers to drive quality.
Traditional data quality management relies on a reactive paradigm. Data engineers write validation checks (using tools like Great Expectations or dbt tests) at the ingestion or transformation layer. : Confluent Schema Registry + quality checks
Contracts explicitly assign responsibility and accountability of the data to those who know it best—the —while giving them the autonomy to manage data as required. A well-defined contract includes machine-readable ownership metadata: team identifiers, escalation paths, and incident management integration.
“Yes,” Maya said, sliding over the PDF printout. “You promise to keep the old column for 30 days and run our validation script. If you break it, your name goes on the Breach Ledger.” Data engineers write validation checks (using tools like
Open-source data quality tools like Great Expectations , Soda , or Deequ constantly check incoming data streams against contract rules, alerting teams instantly if a semantic breach occurs. 5. Overcoming Cultural and Technical Barriers
Driving Data Quality with Data Contracts In modern data engineering, poor data quality acts as a silent tax on innovation. Data pipelines break unexpectedly when upstream software engineers alter database schemas without warning. Downstream data analysts, data scientists, and machine learning models suffer the consequences of broken dashboards, skewed metrics, and corrupted training sets. “Yes,” Maya said, sliding over the PDF printout
This book is essential reading for data engineers, data leaders, architects, and practitioners thinking about their data architecture. Staff engineers, product managers, and software engineering leaders and executives will also find valuable insights.
