AliasAwareOutputOrdering Unary Physical Operators¶

AliasAwareOutputOrdering is an extension of the AliasAwareOutputExpression abstraction for unary physical operators with alias-aware ordering expressions.

Contract¶

Ordering Expressions¶

orderingExpressions: Seq[SortOrder]

SortOrder expressions

Used when:

• AliasAwareOutputOrdering is requested for the output ordering

Implementations¶

• ProjectExec
• SortAggregateExec

Output Data Ordering Requirements¶

outputOrdering: Seq[SortOrder]
