Worked on the aws-mwaa/upstream-to-airflow repository to enhance reliability and compatibility for Databricks integration. Addressed a critical bug in the Databricks Hook by updating the update_job_permission endpoint to remove the '/api' prefix, ensuring alignment with the latest Databricks SDK. This change reduced integration errors and improved the stability of downstream DAGs dependent on this endpoint. Developed and incorporated a regression test to verify the correct behavior of the update_job_permission flow, contributing to improved code quality and test coverage. Utilized Python for backend development, focusing on robust API integration and comprehensive testing to support maintainers and end users.
