Worked on the potiuk/airflow repository to enhance Power BI dataset refresh workflows by introducing a wait_for_completion parameter to the PowerBIDatasetRefreshOperator. This addition enabled both synchronous and asynchronous refresh options, allowing users to tailor data update strategies for their dashboards. Addressed a double-deferral defect to ensure that deferrable execution occurs reliably when waiting for completion, improving the predictability and scalability of data refresh operations. The work focused on backend development using Python and Airflow, resulting in clearer parameter semantics, a more robust deferral path, and reduced operational overhead for maintaining data freshness in Power BI dashboards.
