Kafka Schema Registry Monitoring Guide

Comprehensive guide to monitoring Confluent Schema Registry performance, schema evolution, compatibility checks, and data governance for robust Kafka data pipelines.

Essential Schema Registry Metrics

Monitor these critical aspects of Schema Registry for reliable data governance.

Schema Evolution

Track schema changes, version updates, and compatibility validation across subjects.

API Performance

Monitor API response times, request rates, and caching effectiveness.

Compatibility Issues

Detect schema compatibility violations and breaking changes before deployment.

Schema Governance & Compliance

Implement comprehensive schema governance with automated policy enforcement.

Compatibility Policies

Evolution Strategies

  • • BACKWARD: New schema can read old data
  • • FORWARD: Old schema can read new data
  • • FULL: Both backward and forward compatible
  • • NONE: No compatibility checking

Validation Rules

  • • Required field additions
  • • Type compatibility checks
  • • Default value validation

Schema Metadata

  • Schema registration and versioning tracking
  • Subject-level configuration monitoring
  • Producer and consumer schema usage
  • Schema deletion and cleanup policies
  • Cross-environment schema synchronization
