| DirectQueryOnly | Indicates that queries on the partition should use only the relational data source. | |
| InMemoryOnly | Indicates that queries on the partition should use only the in-memory data store. | |
| InMemoryWithDirectQuery | Indicates that queries against the model can use either the xVelocity in-memory analytics engine (VertiPaq) cache, or the relational data store. The in-memory data store is preferred if both are available. |
Hinweise
Only one partition can be enabled for DirectQuery access at a time. To use a partition in Direct Query mode, the storage mode of the model must have been previously changed to enable DirectQuery mode. For more information, see Partitionen und DirectQuery-Modus (SSAS – tabellarisch).
