public class TestSchemaBuilder
extends DrillTest

The schema builder for tests has grown complex to handle maps, unions, lists and repeated lists. This test verifies that it assembles the various pieces correctly for the various nesting combinations.

Method Detail

testRowBasics

public void testRowBasics()

testRowPreBuilt

public void testRowPreBuilt()

testMapInRow

public void testMapInRow()

Tests creating a map within a row. Also the basic map add column methods.

testUnionInRow

public void testUnionInRow()

Test building a union in the top-level schema. Also tests the basic union add type methods.

testListInRow

public void testListInRow()

Test building a list (of unions) in the top-level schema.

testRepeatedListInRow

public void testRepeatedListInRow()

Test building a repeated list in the top-level schema.

testDictInRow

public void testDictInRow()

Tests creating a dict within a row. Also the basic dict add key and value columns methods.

testVarCharPrecision

public void testVarCharPrecision()

Test methods to provide a width (precision) for VarChar columns. The schema builder does not provide shortcuts for VarChar in lists, unions or repeated lists because these cases are obscure and seldom (never?) used.

testDecimal

public void testDecimal()

Test the ability to specify decimal precision and scale. Decimal is broken in Drill, so we don't bother about decimals in unions, lists or repeated lists, though those methods could be added.

testVarDecimal

public void testVarDecimal()

testVarDecimalOverflow

public void testVarDecimalOverflow()

testMapInMap

public void testMapInMap()

Verify that the map-in-map plumbing works.

testUnionInMap

public void testUnionInMap()

Verify that the union-in-map plumbing works.

testRepeatedListInMap

public void testRepeatedListInMap()

Verify that the repeated list-in-map plumbing works.

testMapInUnion

public void testMapInUnion()

testRepeatedListInUnion

public void testRepeatedListInUnion()

testListInUnion

public void testListInUnion()

testMapInRepeatedList

public void testMapInRepeatedList()

testRepeatedListInRepeatedList

public void testRepeatedListInRepeatedList()

Test that repeated lists can be nested to provide 3D or higher dimensions.

testRepeatedListShortcut

public void testRepeatedListShortcut()

testStandaloneMapBuilder

public void testStandaloneMapBuilder()

testStandaloneRepeatedListBuilder

public void testStandaloneRepeatedListBuilder()

testStandaloneUnionBuilder

public void testStandaloneUnionBuilder()
