abstract class FileOperations[V] extends Serializable with HasDisplayData

Abstracts IO operations for file-based formats.

Since the SMB algorithm doesn't support org.apache.beam.sdk.io.Source splitting, I/O operations must be abstracted at a per-record granularity. Reader and Writer must be Serializable to be used in SortedBucketSource and SortedBucketSink transforms.
