Automatic Data Contracts with LLMs: How to Ensure Compliance and Mitigate Potential Risks
The Data Contract Bottleneck Every data engineers knows the pain of broken pipelines. A schema changes upstream, dashboards fail, and Slack threads turn into finger-pointing sessions. At the center of the chaos lies one missing piece clear, enforceable data contracts. Traditionally, contracts have been defined manually, requiring constant updates and communication between producers and consumers. This slows down teams and leaves plenty of room for error. Enter Large Language Models (LLMs). They promise a new way forward: automatic data contracts that generate and maintain schema and quality rules without endless human intervention. But is this the future of frictionless data engineering, or just another source of hidden risks? Let’s break it down. What Are Data Contracts and Why They Matter At their core, data contracts are agreements that define: Schema: the structure and types of fields in a dataset Semantics: what the fields mean in practice Quality expectations: t...
