Question

How do you clean up or optimize a Power BI report connected via a live connection to a dataset?

I’m working on a Power BI report connected through a live connection to a dataset, and I’m looking for guidance on how to optimize or clean up the report to improve performance and manage resources effectively.

Answer 1

To optimize a Power BI report connected via a live connection:

1. Limit visual complexity: Reduce the number of visuals on a page to improve load times.

2. Use aggregation tables: Implement pre-aggregated tables in the dataset for faster queries.

3. Minimize queries: Avoid excessive DAX calculations in visuals; use efficient DAX formulas.

4. Optimize queries: Ensure the underlying dataset queries are efficient, leveraging filters and aggregations.

5. Reduce data volume: Limit the amount of data being loaded by applying filters at the dataset or report level.

6. Use DirectQuery best practices: Apply caching or incremental data refresh if possible to reduce live query load.

These steps help reduce resource consumption and improve performance.
