-----------------------------------

             Summary: Make dist flatten rocksdbjni
                 Key: KAFKA-10380
                 URL: https://issues.apache.org/jira/browse/KAFKA-10380
             Project: Kafka
          Issue Type: Task
          Components: build
    Affects Versions: 2.6.0
            Reporter: Adrian Cole


I was looking for ways to reduce the size of our Kafka image, and the most notable opportunity is handling rocksdbjni differently. It is currently a 15MB jar.

As mentioned in its description rocksdbjni includes binaries for a lot of OS choices.

du -k librocksdbjni-*
7220	librocksdbjni-linux-aarch64.so
8756	librocksdbjni-linux-ppc64le.so
7220	librocksdbjni-linux32.so
7932	librocksdbjni-linux64.so
5440	librocksdbjni-osx.jnilib
4616	librocksdbjni-win64.dll


It may not seem obvious in normal dists, which aim to work for many operating systems what is a problem here. When creating docker images, we currently would need to repackage this to scrub out the irrelevant OS items or accept files larger than alpine itself.

While this might be something to kick back to rocksdb. having some options here would be great.
