public boolean isBufferedOperator(QueryContext queryContext)

Description copied from class: AbstractBase

Any operator that supports spilling should override this method (and return true)

Specified by:

isBufferedOperator in interface PhysicalOperator

Overrides:

isBufferedOperator in class AbstractBase

Parameters:

queryContext -

Returns:

false
