During March 2026, this developer focused on enhancing the reliability of the Postgres CDC Connector within the apache/seatunnel repository. They addressed a critical issue in replication slot management by ensuring the connector skips slot creation when existing slot information is detected, effectively preventing duplicate-slot errors. Their work involved refining error handling through validation of specific SQLSTATE codes, which increased the resilience of CDC workflows. Utilizing Java and PostgreSQL, the developer contributed to stabilizing Connector-V2 behavior, reducing risky state transitions and improving maintainability. The depth of their backend development work laid a solid foundation for future improvements in CDC functionality.
