This library requires a Java 22+ virtual machine containing the `sun.misc.Unsafe` interface running on a little endian platform.

# Configuration

Temporary directory used to unpack and load native libraries can be configured using the `aircompressor.tmpdir` system property,
with a default value of `java.io.tmpdir`. This is useful when the default temporary directory is mounted as `noexec`.

Loading of native libraries can be disabled entirely by setting the `io.airlift.compress.v2.disable-native` system property.

# Users

This library is used in projects such as Trino (https://trino.io), a distributed SQL engine.
