All Implemented Interfaces:

Serializable, Cloneable, VectorizationContextRegion, Node

public class VectorSMBMapJoinOperator
extends SMBMapJoinOperator
implements VectorizationContextRegion

VectorSMBJoinOperator. Implements the vectorized SMB join operator. The implementation relies on the row-mode SMB join operator. It accepts a vectorized batch input from the big table and iterates over the batch, calling the parent row-mode implementation for each row in the batch.

Method Detail

processOp

public void processOp(Object row,
                      int tag)
               throws HiveException

Description copied from class: Operator

Process the row.

Overrides:

processOp in class SMBMapJoinOperator

Parameters:

row - The object representing the row.

tag - The tag of the row usually means which parent this row comes from. Rows with the same tag should have exactly the same rowInspector all the time.

Throws:

HiveException

closeOp

public void closeOp(boolean aborted)
             throws HiveException

Description copied from class: CommonJoinOperator

All done.

Overrides:

closeOp in class SMBMapJoinOperator
