org.apache.drill.exec.physical.resultSet.impl.TestResultSetLoaderMapArray

public class TestResultSetLoaderMapArray
extends SubOperatorTest

Test map array support in the result set loader.

The tests here should be considered in the "extra for experts" category: run and/or debug these tests only after the scalar tests work. Maps, and especially repeated maps, are very complex constructs not to be tackled lightly.

Method Detail

testBasics

public void testBasics()

testNestedArray

public void testNestedArray()

testDoubleNestedArray

public void testDoubleNestedArray()

Test a doubly-nested array of maps.

testOverwriteRow

public void testOverwriteRow()

Version of the {#link TestResultSetLoaderProtocol#testOverwriteRow()} test that uses nested columns inside an array of maps. Here we must call start() to reset the array back to the initial start position after each "discard."

testOmittedValues

public void testOmittedValues()

Check that the "fill-empties" logic descends down into a repeated map.

testCloseWithoutHarvest

public void testCloseWithoutHarvest()

Test that memory is released if the loader is closed with an active batch (that is, before the batch is harvested.)
