A Java port of Google's Snappy fast compressor/decompressor, using JNI to achieve near-native performance. It bundles native libraries for Windows, Mac, and Linux and supports compression of Java primitive arrays plus the Snappy framing format.

Use cases

• compress large byte arrays quickly in Java
• add Snappy compression to a JVM data pipeline
• compress primitive arrays like int[] or double[] efficiently
• read or write Snappy framing-format streams
• reduce memory footprint of streaming compression in a server app

When to choose

• you need very fast compression/decompression (hundreds of MB/s) in Java
• compression ratio is less important than speed
• you want a portable, drop-in JAR with bundled native libraries
• you need OSGi or multi-classloader-safe native loading

When to avoid

• you need maximum compression ratio rather than speed (use gzip, bzip2, or zstd)
• you need a pure-Java implementation without native dependencies
• your platform lacks a prebuilt native library
