  • Hi

    Azure Data Lake VS tools has provided the capability for customers to decide what's the best number AU for this job. We also have a build-in model so that customers can play with it to understand the execution time vs number of AUs. You can suggest customers to run a job once and use this tool to analyze it.

    More details can be found here:

    The number of vertices is a compiler decision by considering multiple factors, like number of files and file size. If you have multiple big files, we would suggest from 1 AU for 1 GB data.
