- Certain data types and complex delta table column types are not supported.
- At the moment, it is not possible to use calculated columns and calculated tables.
- The values in string columns can't exceed 4,000 Unicode characters in length.
- Restrictions on mixing Direct Lake tables with other types, like Import or DirectQuery, within the same model.
- Inability to query tables based on T-SQL-based views in Direct Lake mode; such queries revert to DirectQuery mode.
- Some limitations in embedded scenarios and the unsupported use of complex relationships, calculated columns, and tables.
