Understanding dataset storage modes

As you may have already guessed, dataset storage modes refer to whether the data in a dataset is cached in the memory or not. With that in mind, from a dataset perspective, there are three different modes, as outlined next:

Import: When the whole data is cached in the memory. In this mode, all tables are in the Import storage mode setting.
DirectQuery: When the data is not cached in the memory. In this mode, all tables are in the DirectQuery storage mode setting.
Composite (Mixed): When a portion of data is cached in the memory, while the rest is not. In this mode, some tables are in the Import storage mode setting; other tables are in DirectQuery storage mode or the Dual storage mode setting.
