Hello, we would like to vendor the current stable-4.x branch of jemalloc in Arrow C++ as we rely on the current latest commit for working with it. As the performance benefits of jemalloc are quite large, this is a burden, we would be ready to take. As jemalloc is a non-Apache project, we would need to be careful of the IP. jemalloc itself is licensed under the 2-clause BSD license.
Would it be ok to include jemalloc sources alongside in the Arrow tarball with LICENSE amended accordingly? Do we need to also put Apache License headers in all of jemalloc files? Is this even possible or would we need a code donation for the whole process? Uwe
