Data Governance for Apache Kafka with Schema Registry and Data Contracts

Good data quality is one of the most critical requirements in decoupled architectures, like microservices or data mesh. Apache Kafka became the de facto standard for these architectures. But Kafka is a dumb broker that only stores byte arrays. The Schema Registry enforces message structures. This blog post looks at enhancements to leverage data contracts for policies and rules to enforce good data quality on field-level and advanced use cases like routing malicious messages to a dead letter queue.

From point-to-point and spaghetti to decoupled microservices with Apache Kafka

Point-to-point HTTP / REST APIs create tightly couple services. Data lakes and lakehouses enforce a monolithic architecture instead of open-minded data sharing and choice of the best technology for a problem. Hence, Apache Kafka became the de facto standard for microservice and data mesh architectures. And data streaming with Kafka complementary (not competitive!) to APIs, data lakes / lakehouses, and other data platforms.
