Cloud Fetch is a feature introduced in Databricks Runtime 8.3 and Simba ODBC 2.6.17 driver that significantly improves data transfer efficiency from Databricks to BI tools like Power BI. It achieves this by fetching data in parallel via cloud storage such as AWS S3 and Azure Data Lake Storage, which brings the data faster to BI tools. In experiments using Cloud Fetch, a 10x speed-up in extract performance was observed due to parallelism. This feature is available in Databricks SQL and interactive Databricks clusters deployed with Databricks Runtime 8.3 or higher both on Azure Databricks and Amazon.
In regards Qlik Sense there is no explicit information that confirms there is compatibility.
