public class TestRowBatchMerger
extends SubOperatorTest

Test the row batch merger by merging two batches. Tests both the "direct" and "exchange" cases. Direct means that the output container contains the source vector directly: they are the same vectors. Exchange means we have two vectors, but we swap the underlying Drillbufs to effectively shift data from source to destination vector.
