Package edu.stanford.slac.archiverappliance.plain.parquet

Class NIOInputFile

java.lang.Object

edu.stanford.slac.archiverappliance.plain.parquet.NIOInputFile

All Implemented Interfaces:

org.apache.parquet.io.InputFile

public class NIOInputFile
extends Object
implements org.apache.parquet.io.InputFile

An InputFile implementation that only uses java.nio.* interfaces for I/O operations. The LocalInputFile implementation in upstream parquet-mr currently falls back to the old-school java file I/O APIs (via Path#toFile) which won't work with nio remote FileSystems such as an S3 FileSystem implementation.
