      That is true, but my approach would be to not model based on the exceptions. Rather model for the 80%+ of use cases and create alternative solutions for the exceptions.

    Hey Bas,
    Thanks again for the video, very informative.
    I just wanted to point out :
    Step 3: it would be much preferred to push all of the calculations, group by functions to the DataMart in case the user's have one.
    Step 10: the incremental refresh kind of will help with the import mode since you only import your data once then in the workspace it will create partitions of that data that will be stored and not changed and depending on how you want the data to be refreshed and when you know for example that your data after 2 weeks will not change you can set it up and your data will be stored in the workspace.
    Thanks again for the video !!
    PS: when will you do a video about the power bi extension you use and how you use them, it will be great !!

    This was great thanks. I still battle to understand some basic things, like when you you create relationships (is it necessary for a type star model?) versus when you you do joins/merges? For example if you do a merge in PQ then that's a join (?), but if you create relationships using the model view and use a field from another table in a visual is that a join too?

    Cheers for the video! Do you have any more tips for those who can't use external tools like bravo due to security reasons? Recently started at a large company and need to optimise some reports that are very large due to scope creep, is it just a case of looking at all the visuals and checking to see what columns aren't used etc?

  • @raghunb
    @raghunb 18 днів тому

    Some more optimizations that I would recommend:
    1. Use Binary.Buffer, List.Buffer and Table.Buffer judiciously. They significantly speed up Power Query refreshes.
    2. Operate on List compared to Tables in Power Query. List operations are much faster. After transformation on list, the data can easily be transformed into Table using power query function Table.FromList
    3. Perform transformation in DAX as much as possible. They are much faster on large tables compared to Power Query
    4. Use incremental refresh where older data is not modified. This will speed up data refreshes

      @raghunb 18 днів тому

      @@HowtoPowerBI I think, I should qualify my comment further. Where query folding is possible e.g. data sources that support SQL queries, its probably better to move the transformation to the source of the query. In other cases e.g. REST API requests, it's better to let the power query to construct the tables with the responses and let DAX do the transformations
