CompressionCodec

trait CompressionCodec extends AnyRef

:: DeveloperApi :: CompressionCodec allows the customization of choosing different compression implementations to be used in block storage.

Note: The wire protocol for a codec is not guaranteed compatible across versions of Spark. This is intended for use as an internal compression utility within a single Spark application.
