New licensing for Akka
Hi all!
It seems Akka have announced a licensing change
https://www.lightbend.com/blog/why-we-are-changing-the-license-for-akka
If I understand correctly, this could end-up increasing cost a lot for
companies using Flink in production. Do you know if the Flink developers
have any initial reaction as to how this could be handled (using a Fork?
moving out of akka, even though it's probably incredibly complex?)? Are we
right to assume that this license applies when using akka through Flink?
Thanks a lot!
Robin

There is some more discussion going on in the related PR [1]. Based on the
current state of the discussion, akka 2.6.20 will be the last version under
Apache 2.0 license. But, I guess, we'll have to see where this discussion
is heading considering that it's kind of fresh.

We'll have to look into it.
The license would apply to usages of Flink.
That said, I'm not sure if we'd even be allowed to use Akka under that
license since it puts significant restrictions on the use of the software.
If that is the case, then it's either use a fork created by another
party or switch to a different library.

[NOTICE] Blog post regarding Akka's licensing change
Posted by Chesnay Schepler <ch...@apache.org>.
Hello,
You may have heard about a recent change to the licensing of Akka.
We just published a blog-post regarding this change and what it means
for Flink.
https://flink.apache.org/news/2022/09/08/akka-license-change.html
TL;DR:
Flink is not in any immediate danger and we will ensure that users are
not affected by this change.
The licensing of Flink will not change; it will stay Apache-licensed and
will only contain dependencies that are compatible with it.
We will not use Akka versions with the new license.
Regards,
Chesnay

Just to squash concerns, we will make sure this license change will not
affect Flink users in any way.
