Enum Class FileCompressionType

java.lang.Object

java.lang.Enum<FileCompressionType>

org.apache.datafusion.FileCompressionType

All Implemented Interfaces:

Serializable, Comparable<FileCompressionType>, Constable

public enum FileCompressionType
extends Enum<FileCompressionType>

Compression of a file-format source. Shared by CsvReadOptions and NdJsonReadOptions (and any future format that exposes the same set of compressions). Variant names match DataFusion's Rust FileCompressionType so they round-trip across JNI.
