Mickael Maison commented on KAFKA-19951:
----------------------------------------
Looking at the LZ4Factory.fastestInstance() method, it should return the native
implementation, not the Java implementation, on all platforms where the JNI
bindings are available.
The lz4-java JAR contains the following bindings:
{noformat}
├── darwin
│ │ │ ├── aarch64
│ │ │ └── x86_64
│ │ ├── linux
│ │ │ ├── aarch64
│ │ │ ├── amd64
│ │ │ ├── i386
│ │ │ ├── ppc64le
│ │ │ └── s390x
│ │ └── win32
│ │ └── amd64
{noformat}
While Kafka does not publish a list of supported platforms, these bindings
cover the most used common platforms.
> switch lz4-java to at.yawk.lz4 version due to CVE
