Classes in io.druid.segment.data used by io.druid.benchmark

Class and Description
CompressionFactory.LongEncodingStrategy The compression of decompression of encodings are separated into different enums.
CompressionStrategy Compression strategy is used to compress block of bytes without knowledge of what data the bytes represents.
