Java 11 and the future of Apache Ignite

[Kamil Misuth <ki...@ethome.sk>]

Hi, since Java 11 is not only about new features but also about new 
licensing terms and new release schedule, I would like to ask about the 
long term goals of the Apache Ignite project.

Question 1:
With the new Java release model, it seems Oracle will provide security 
fixes and backports to the current LTS release (11 in this case) only to 
paying customers. All other users will need to track OpenJDK and upgrade 
every 6 months to the newest Java release to get the security fixes. 
Will Apache Ignite track the new release schedule of OpenJDK and try to 
keep up with every new Java release every 6 months?

Question 2:
OpenJ9 is not currently listed under tested JDKs. Even though it is a 
derivative of IBM JDK, will it receive official testing like Oracle, IBM 
and OpenJDK?

Question 3:
Ignite Prerequisites documentation page says Ignite was tested on Java 8 
and later. Does it mean there are no problems with Ignite's 
Unsafe/GridUnsafe use in Java 11?

Question 4:
Java 11 ships with ZGC which should support up to TB heaps, minimal 
pause times and concurrent compaction. Cold storage support for rarely 
accessed objects may be added as well. To me this seems like a 
competition to Ignite's durability enabled memory-centric design (minus 
clustering). Isn't that so?

Thank you.

Regards,
Kamil

Hi,

I agree with Ilya, Java 11 is currently under active discussions on
dev.list. You can look at archives using
https://lists.apache.org/list.html?dev@ignite.apache.org

I can see a number of tickets, which created for support/test features of
the newest Java.

Sincerely,
Dmitriy Pavlov

Hello!

This might be more suited to developers list. I will answers from user
perspective:

1) I guess that all LTS releases will be supported (which are every 6th
release?). Intermediate releases will receive some testing in releases that
they are released, but will not be a primary target.

2) Maybe if RedHat and IBM have success in promoting their offerings, there
will be official support or even migration of development process towards
that. It's to early to tell.

3) This was under assumption that JVM remains largely backwards
compatibility, which is what they're going away from. So you should not
expect that Ignite will run out of box on later releases than ones it was
developed for.

4) It is too early to say.

Regards,
