Exploring query types – Connecting to Data Sources
Exploring query types When Power BI connects to any data source, it makes one of two types of connections or queries. DirectQuery The first type is called DirectQuery, or a live connection to the data. This means that Power BI is storing credentials and a connection string to the data source. For example, this could […]
Power BI datasets – Connecting to Data Sources
Power BI datasets Data used in Power BI reports uses a Power BI dataset. Power BI datasets are basically a connection string and credentials that Power BI uses to connect to a data source. Every report that is created in Power BI must have a dataset associated with it. This ensures the report has data […]
Query performance tuning – Connecting to Data Sources
Query performance tuning When considering optimizing the performance of Power BI queries, there are a few places to start, and the recommendation is to look at each as a layer of performance tuning to undertake. These layers include reducing the size of the data, optimizing DirectQuery (when used), and optimizing composite models (when used). Reducing […]

DirectQuery optimization – Connecting to Data Sources
DirectQuery optimization When using DirectQuery, it’s important to remember that the total performance experienced is dependent upon both Power BI and the underlying data source. Many times, Power BI reports will use a data warehouse such as Azure Synapse Analytics as the data source and for enterprise data warehouses like this, there are several considerations […]
Composite model optimization – Connecting to Data Sources
Composite model optimization When something is composite, it is made up of more than one thing. Composite models in Power BI mean that a single data model contains data from multiple sources, and these can be both Import and DirectQuery. Note that composite models can’t be used for every data source type, and they introduce […]
