Modifies how filters are applied while evaluating a GROUPCROSSAPPLY or GROUPCROSSAPPLYTABLE function.

Syntax

SHADOWCLUSTER ( <TableExpression> )

Parameter	Attributes	Description
TableExpression		Any table expression.

Table An entire table or a table with one or more columns.

This function is mainly used internally by Power BI to query remote models in composite models.

You use SHADOWCLUSTER within the context GROUPCROSSAPPLY and GROUPCROSSAPPLYTABLE functions, to override the standard behavior of those functions.

When a table is marked as SHADOWCLUSTER, it is marked internally as a “shadow” table expression so that it is only enabled in an ALLSELECTED context.
