Class InputBatch

java.lang.Object

org.apache.drill.exec.physical.impl.xsort.BatchGroup

org.apache.drill.exec.physical.impl.xsort.InputBatch

All Implemented Interfaces:

AutoCloseable, Iterable<VectorWrapper<?>>, VectorAccessible

public class InputBatch
extends BatchGroup

The input batch group gathers batches buffered in memory before spilling. The structure of the data is:

• Contains a single batch received from the upstream (input) operator.
• Associated selection vector that provides a sorted indirection to the values in the batch.
