About:
Maxwell is a daemon that reads MySQL binlogs and writes row-level updates to Kafka as JSON. It captures INSERT, UPDATE, and DELETE operations in real-time, enabling reliable change data capture (CDC) for downstream consumers. This allows you to easily stream database changes to other systems for analytics, caching, or microservices integration.
Key Features:
  • Real-time CDC from MySQL to Kafka
  • Outputs row-level changes as JSON
  • Supports schema evolution and recovery
  • Minimal performance impact on source database
Use Cases:
  • Populating search indexes like Elasticsearch from MySQL
  • Syncing caches or microservices with database changes
  • Real-time analytics pipelines and data warehousing
  • Building event-driven architectures
Alternatives:
  • Debezium – More complex Kafka Connect-based platform vs Maxwell's simpler standalone daemon
  • Canal – Java-based CDC tool with similar functionality, often used in Java-centric ecosystems
