Method Details

getNewWithChildren

public PhysicalOperator getNewWithChildren(List<PhysicalOperator> children)

Description copied from interface: PhysicalOperator

Regenerate with this node with a new set of children. This is used in the case of materialization or optimization.

Parameters:

children -

isRowKeyJoin

public boolean isRowKeyJoin()

getJoinControl

public int getJoinControl()

getSubScanForRowKeyJoin

public SubScan getSubScanForRowKeyJoin()

setSubScanForRowKeyJoin

public void setSubScanForRowKeyJoin(SubScan subScan)

flipIfRight

public HashJoinPOP flipIfRight()

getOperatorType

public String getOperatorType()

setMaxAllocation

public void setMaxAllocation(long maxAllocation)

Description copied from class: AbstractBase

Any operator that supports spilling should override this method

Specified by:

setMaxAllocation in interface PhysicalOperator

Overrides:

setMaxAllocation in class AbstractBase

Parameters:

maxAllocation - The max memory allocation to be set

isBufferedOperator

public boolean isBufferedOperator(QueryContext queryContext)

The Hash Aggregate operator supports spilling

Specified by:

isBufferedOperator in interface PhysicalOperator

Overrides:

isBufferedOperator in class AbstractBase

Parameters:

queryContext -

Returns:

true (unless a single partition is forced)

setRuntimeFilterDef

public void setRuntimeFilterDef(RuntimeFilterDef runtimeFilterDef)

getRuntimeFilterDef

public RuntimeFilterDef getRuntimeFilterDef()
