A Java library providing LZ4 compression and decompression with fast, high-compression, and interoperable frame modes. It offers JNI bindings to the C implementation plus pure-Java and Unsafe-based ports, all producing interchangeable streams.
Use cases
- compress data in a Java application with LZ4
- read LZ4 frame streams produced by other languages or the lz4 CLI
- speed up serialization of large in-memory datasets
- choose between JNI speed and pure-Java portability for compression
- decompress LZ4 streams with low memory overhead
When to choose
- you need very fast compression/decompression on the JVM
- you need interoperable LZ4 frame streams across languages
- you want a choice of JNI, Unsafe, or pure-Java implementations
When to avoid
- starting a new project - the official project is discontinued; use the community fork (yawkat/lz4-java)
- you need maximum compression ratio rather than speed
- you need a non-JVM language
