Fields

DirectQueryOnly 2

Indicates that queries on the partition should use only the relational data source.

InMemoryOnly 1

Indicates that queries on the partition should use only the in-memory data store.

InMemoryWithDirectQuery 0

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.

Remarks
