org.apache.drill.exec.physical.impl.scan.v3.schema.TestScanSchemaTrackerMaps

public class TestScanSchemaTrackerMaps
extends BaseTest

Maps add considerable complexity to the scan schema tracker, turning a list of columns into a tree. The projection list, provided schema, defined schema, scan schema, reader schema and missing columns schemas must all be trees, and must all be kept in sync.

Method Detail

testGenericMap

public void testGenericMap()

Test a map projected with just the map name: `m`.

testGenericAndSpecificMap

public void testGenericAndSpecificMap()

Test a map projected with the map name and a specific column: `m`.`x`, `m`. The map is generic: the entire map is projected.

testTwoLevelGenericMap

public void testTwoLevelGenericMap()

testMapWithWildcard

public void testMapWithWildcard()

testMapWithWildcardNoSchemaChange

public void testMapWithWildcardNoSchemaChange()

testSpecificMap

public void testSpecificMap()

Test a specific map column, `m`.`x`, with no schema.

testSpecificMapSubset

public void testSpecificMapSubset()

testGenericMapWithLenientProvidedSchema

public void testGenericMapWithLenientProvidedSchema()

Test a generic map with a lenient provided schema. The schema defines those columns which do exist, but allow other map members to be added.

testGenericMapWithStrictProvidedSchema

public void testGenericMapWithStrictProvidedSchema()

Test a generic map with a strict provided schema. The schema defines those columns which exist, and forbids adding other map members.

testGenericMapWithDefinedSchema

public void testGenericMapWithDefinedSchema()

Test a generic map with a defined schema. The schema exactly defines the map. Since the map projection is generic, it matches whatever columns the defined schema defines.

testSpecificMapWithLenientProvidedSchema

public void testSpecificMapWithLenientProvidedSchema()

Test a specific map column (m.x) with a lenient provided schema. The schema can include columns other than the specific one, but only the specific one will be projected. Note that the projection list, not the provided schema, constrains projection in this case.

testSpecificMapWithStrictProvidedSchema

public void testSpecificMapWithStrictProvidedSchema()

Test a specific map column (m.x) with a strict provided schema. The schema can include columns other than the specific one, but only the specific one will be projected.

testSpecificMapWithDefinedSchema

public void testSpecificMapWithDefinedSchema()

Test a specific map column (m.x) with a defined schema. The defined schema must exactly match the projection list (because it should have been computed from that list.)

testDynamicMapWithDefinedSchema

public void testDynamicMapWithDefinedSchema()

testGenericMapWithStrictSchema

public void testGenericMapWithStrictSchema()

Test a generic map column (m.x) with a defined schema. The defined schema must exactly match the projection list (because it should have been computed from that list.)

testDynamicMapWithStrictSchema

public void testDynamicMapWithStrictSchema()

testGenericMapWithDynamicSchema

public void testGenericMapWithDynamicSchema()

testMapProjectionMismatchLength

public void testMapProjectionMismatchLength()

When a defined schema is given, the map projection list must match the defined schema. Unlike a provided schema, extra columns are not allowed.

testMapProjectionMismatchMembers

public void testMapProjectionMismatchMembers()

When a defined schema is given, the map projection list must match the defined schema. Unlike a provided schema, disjoint columns are not allowed.
