Re: Native persistence and upgrading

[xero <mp...@gmail.com>]

Hi Dimitry and community,
Is this still true? My intention is to do it between versions 2.7.6 and
2.8.1/2.9. Basically, I want to only update the docker image keeping the
volumes so that I can recover the persisted data. I couldn't find
documentation regarding this topic.

On the other hand, release_2.9 introduced Cluster Snapshots. Are these
snapshots version agnostic? or there are some considerations regarding which
versions are compatible with the created snapshot? Could this be an
alternative to solve my issue (upgrading without losing the persisted data)? 

Thanks in advance for the time.

Hello!

All of 2.x are compatible, meaning you can upgrade from 2.x to 2.y, y > x,
while keeping your persistence files.

Yes, I think we should document this somewhere:
https://issues.apache.org/jira/browse/IGNITE-13851

Thanks for the confirmation Stanislav. Is this compatibility kept between
minors as a commitment from the team or is it just specific to the versions
I mentioned?
If this is a backward compatibility feature that you have intentions to
maintain, I think it's worth mentioning that in the documentation because is
a great feature.

Thank you

Yes, you can upgrade from an older version to a newer one and keep the data, it will just work.
You don't really need snapshots for that, although I assume snapshots would also work.
