Legacy cloud data warehouses often collect the results on a leader (aka driver) node, and stream it back to the client. This greatly slows down the experience in your BI tool if you are fetching anything more than a few megabytes of results. > That’s why we’ve reimagined this approach with a new architecture called Cloud Fetch. For large results, Databricks SQL writes results in parallel across all of the compute nodes to cloud storage, and then sends the list of files using pre-signed URLs back to the client. The client then can download in parallel all the data from cloud storage. We are delighted to report up to 10x performance improvement in real-world customer scenarios! We are working with the most popular BI tools to enable this capability automatically. by databricks ### Additional context  ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! -- This is an automated message from the Apache Git Service.
