What is Model Optimization?
Model optimization covers techniques to reduce a data model's size and improve its query speed, such as removing unused columns, choosing efficient data types, and reducing cardinality where possible. Since Power BI's in-memory engine compresses data based on column cardinality, fewer unique values in a column generally means better compression. Optimization matters most as datasets grow into the millions of rows.
