Gather Streams Showplan Operator
The Gather Streams operator is only used in parallel query plans. The Gather Streams operator consumes several input streams and produces a single output stream of records by combining the input streams. The record contents and format are not changed. If this operator is order preserving, all input streams must be ordered.
If the output is ordered, the Argument column contains an ORDER BY:() predicate and the names of columns being ordered.
Gather Streams is a logical operator.
