2.2.4.2.2.6.3 PushedDataSource

  • Article

The PushedDataSource complex type represents a chunk of tabular data being pushed into the server. This is in contrast to RelationalDataSource and OlapDataSource, where the server pulls the data by sending queries to the data source.

PushedDataSource cannot be specified in a Create or Alter command. It can be used only within a Process command. For more information, see section 3.1.4.3.2.1.1.6.
