Freshness SLA missed. Null values slipped through. Nobody noticed until downstream.</p> <p>dcvpg lets you define data contracts as code and enforces them automatically:</p> <p>✅ Schema drift detection — catch column drops, type changes before they hit prod<br> ✅ Quality rule validation — nullability, regex, range checks, custom rules<br> ✅ Freshness SLA monitoring — alert when your pipeline goes stale<br> ✅ Pipeline gate integration — block bad data at the source</p> <p>Built for data engineers who are tired of being the last to know when something breaks.</p> <p>100% open source. Python. YAML-based contracts. CI/CD friendly.</p> <p>👉 github.com/pasindudilshan1/dcvpg<br> <a href="https://pasindudilshan1.github.io/dcvpg/" rel="noopener noreferrer">https://pasindudilshan1.github.io/dcvpg/</a></p> <p>Drop a ⭐ if this solves a problem you've lived.</p> <h1> DataEngineering #OpenSource #DataContracts #PipelineQuality #Python #DataQuality </h1> dataengineering opensource showdev testing
