This library contains implementations of
Zstandard (Zstd),
LZ4,
Snappy, and
LZO written in pure Java. They are
typically 10-40% faster than the JNI wrapper for the native libraries.
Additionally implementations of GZIP and Deflate using the Java built-in library,
and pure Java BZip2 implementations are provided for ease of integrations with
systems that need these algorithms.
In addition to the raw block encoders, there are implementations of the Hadoop CompressionCodec (Streaming) for each algorithm. They are typically 300% faster than the JNI wrappers.
This library requires a Java 1.8+ virtual machine containing the sun.misc.Unsafe interface running on a little endian platform.
This library is used in projects such as Trino (https://trino.io), a distributed SQL engine.
