Worked on enhancing the stability and transactional reliability of the BinlogConnectorConnection in the debezium/debezium repository. Focused on backend development using Java and database management skills, the work addressed issues with stale pool connections by ensuring reconnection before snapshotting, which reduced snapshot failures. Transactional integrity was improved by disabling auto-commit during connection initialization, enforcing stricter transactional boundaries. Additionally, the approach to table size estimation was refined by switching to the execute() method, resulting in more consistent and accurate sizing. These targeted improvements contributed to more robust snapshot operations and reduced flaky behavior in the connector’s database interaction layer.
