## What is the purpose of the change Implement File source ORC Vectorized Reader ## Brief change log The `AbstractOrcFileInputFormat` reference from https://github.com/apache/flink/pull/13401 - The base for ORC readers, Implements the reader initialization, vectorized reading, and pooling of column vector objects. The format of `Row` and `GenericRow` can be implemented based on this class. - Use `OrcShim` to do orc related operations. - Use both `offset` and `recordsAfterOffset` in `CheckpointedPosition` for better fitting the concept of `RecordReader`. Avoid skipping some of the middle rows when using pushdown filter. The `OrcColumnarRowFileInputFormat`: - This class can add extra fields through `ColumnBatchFactory`, for example, add partition fields. - Provides `ColumnarRow` as a view of column batch for high performance. ## Verifying this change `OrcColumnarRowFileInputFormatTest` ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): no - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: no - The serializers: no - The runtime per-record code paths (performance sensitive): no - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn/Mesos, ZooKeeper: no - The S3 file system connector: no ## Documentation - Does this pull request introduce a new feature? yes - If yes, how is the feature documented?
