Worked on the debezium/debezium repository to enhance MariaDB JSON support within the JDBC Sink Connector. Developed a dedicated JsonType class to handle JSON data types in MariaDB and integrated it into the MariaDbDatabaseDialect, ensuring seamless data mapping. Addressed a bug that previously prevented correct JSON insertion into MariaDB, thereby improving data fidelity and reliability in the sink path. Added comprehensive unit tests to validate the new functionality and strengthen test coverage. Utilized Java and database management skills, with a focus on unit testing, to deliver maintainable improvements that expand dialect coverage and support robust end-to-end JSON data flow.
