Worked on the Duansg/hertzbeat repository to enhance backend stability and data integrity over a two-month period, focusing on Java-based bug fixes. Addressed a critical issue in the JpaDatabaseDataStorage path by converting NaN values to NULL before persisting numeric data in MySQL, which prevented WrongArgumentException and improved the reliability of database operations. Additionally, improved service discovery robustness by handling NullPointerExceptions, defaulting monitor targets to 'unknown' when host information was unavailable, and strengthening host validation logic. These targeted changes in backend development and database management contributed to higher application uptime and reduced runtime errors, ensuring more consistent and reliable service behavior.
