Worked on the Debezium/debezium repository to deliver a feature enhancing log mining accuracy by expanding the session SCN range used in CTE queries. This update improved the reliability and correctness of log-mined data by ensuring that the full session SCN range is considered during query execution. The implementation involved Java for backend logic, with a focus on database management and comprehensive unit testing to ensure code quality and release readiness. The work was tracked through a signed-off pull request and commit, reflecting a methodical approach to feature delivery and adherence to established development and review workflows within the project.
