Anthony Olazabal developed a Database Protocol Adapter for the hivemq-edge repository, enabling HiveMQ Edge to connect with PostgreSQL, MySQL, and MS SQL databases. He implemented the adapter using Java and Kotlin, focusing on robust database integration and efficient data retrieval. The solution included configurable polling intervals and comprehensive error handling, allowing reliable and fault-tolerant data ingestion. By publishing database records directly to MQTT topics, Anthony’s work reduced data-access latency and expanded enterprise integration capabilities. The adapter’s design leveraged HikariCP for connection management and Gradle for build automation, establishing a scalable bridge between diverse databases and MQTT-based workflows.
