Type Members

1.  class OrcArrayColumnVector extends OrcColumnVector

   A column vector implementation for Spark's ArrayType.

2.  class OrcAtomicColumnVector extends OrcColumnVector

   A column vector implementation for Spark's AtomicType.

3.  abstract class OrcColumnVector extends ColumnVector

   A column vector interface wrapping Hive's ColumnVector.

   A column vector interface wrapping Hive's ColumnVector.

   Because Spark ColumnarBatch only accepts Spark's vectorized.ColumnVector, this column vector is used to adapt Hive ColumnVector with Spark ColumnarVector.

4.  class OrcColumnarBatchReader extends RecordReader[Void, ColumnarBatch]

   To support vectorization in WholeStageCodeGen, this reader returns ColumnarBatch.

   To support vectorization in WholeStageCodeGen, this reader returns ColumnarBatch. After creating, initialize and initBatch should be called sequentially.

5.  class OrcDeserializer extends AnyRef

   A deserializer to deserialize ORC structs to Spark rows.

6.  class OrcFileFormat extends FileFormat with DataSourceRegister with Serializable

   New ORC File Format based on Apache ORC.

7.  trait OrcFiltersBase extends AnyRef

   Methods that can be shared when upgrading the built-in Hive.

8.  class OrcMapColumnVector extends OrcColumnVector

   A column vector implementation for Spark's MapType.

9.  class OrcOptions extends Serializable

   Options for the ORC data source.

10.  class OrcSerializer extends AnyRef

    A serializer to serialize Spark rows to ORC structs.

11.  class OrcStructColumnVector extends OrcColumnVector

    A column vector implementation for Spark's StructType.
