public PhysicalOperator getPhysicalOperator(PhysicalPlanCreator creator)
                                     throws IOException

Specified by:

getPhysicalOperator in interface Prel

Throws:

IOException

getSupportedEncodings

public BatchSchema.SelectionVectorMode[] getSupportedEncodings()

Description copied from interface: Prel

Supported 'encodings' of a Prel indicates what are the acceptable modes of SelectionVector of its child Prel

Specified by:

getSupportedEncodings in interface Prel

getEncoding

public BatchSchema.SelectionVectorMode getEncoding()

FilterPrel adds an SV2 (TWO_BYTE mode SelectionVector).

Specified by:

getEncoding in interface Prel

needsFinalColumnReordering

public boolean needsFinalColumnReordering()

Specified by:

needsFinalColumnReordering in interface Prel

prepareForLateralUnnestPipeline

public Prel prepareForLateralUnnestPipeline(List<org.apache.calcite.rel.RelNode> children)

Description copied from interface: Prel

If the operator is in Lateral/Unnest pipeline, then it generates a new operator which knows how to process the rows accordingly during execution. eg: TopNPrel -> SortPrel and LimitPrel Other operators like FilterPrel, ProjectPrel etc will add an implicit row id to the output.

Specified by:

prepareForLateralUnnestPipeline in interface Prel
