Method Detail

testNoReaders

public void testNoReaders()

Simplest possible do-nothing, default config case. Scan produces no valid schema.

testEarlyEOF

public void testEarlyEOF()

Single reader, late schema, early EOF. The scan never has a valid schema in this case.

testNullReader

public void testNullReader()

Single reader empty schema, EOF on first next(). Since both no schema and no rows, we assume this to be a null (not empty) result set, so no output schema.

testNullReaderWithSchema

public void testNullReaderWithSchema()

Single reader early schema, EOF on first next(). Since this is an early-schema reader, there is an output schema even without any rows.

testEarlySchemaOneBatch

public void testEarlySchemaOneBatch()

Test SELECT * from an early-schema table of (a, b)

testEarlySchemaTwoBatches

public void testEarlySchemaTwoBatches()

testLateSchemaOneBatch

public void testLateSchemaOneBatch()

Single reader late schema, one batch.

testLateSchemaTwoBatches

public void testLateSchemaTwoBatches()

testEarlySchemaWithProject

public void testEarlySchemaWithProject()

Test SELECT a, c FROM table(a, b)

testLateSchemaWithProject

public void testLateSchemaWithProject()

Test SELECT a, c FROM table(a, b) c will be null

testEarlySchemaReorder

public void testEarlySchemaReorder()

Test SELECT b, a FROM table(a, b)

testEarlySchemaWithProjectNone

public void testEarlySchemaWithProjectNone()

testLateSchemaWithCustomType

public void testLateSchemaWithCustomType()

Test SELECT * from an early-schema table of () (that is, a schema that consists of zero columns.

testEarlySchemaSubset

public void testEarlySchemaSubset()

Test SELECT a FROM table(a, b)

testEarlySchemaEmpty

public void testEarlySchemaEmpty()

Test SELECT * from an early-schema table of () (that is, a schema that consists of zero columns.

testEarlySchemaEmptyWithProject

public void testEarlySchemaEmptyWithProject()

Test SELECT a from an early-schema table of () (that is, a schema that consists of zero columns.
