--------------------------------------------
Summary: Provide compatibility version matrix for rolling upgrade
Key: IGNITE-27182
URL: https://issues.apache.org/jira/browse/IGNITE-27182
Project: Ignite
Issue Type: New Feature
Reporter: Aleksandr Chesnokov
Assignee: Aleksandr Chesnokov
We currently support only two migration patterns:
* X.Y.Z → X.Y.(Z+1)
* X.Y.Z → X.(Y+1).0
These rules are too restrictive. They limit how users can upgrade and create
obstacles for forks that introduce their own versioning schemes.
{*}Proposal{*}: introduce an admin-managed compatibility matrix.
This matrix defines which source and target versions are compatible. Forks will
be able to define their own version formats and simply register compatibility
versions
Admins would be able to add, edit, or remove compatibility rules, enabling a
fully customizable upgrade model
