What is the new `Rolling Upgrade check` check for PR? What about it?

I noticed there's a new `Rolling Upgrade check` test for PR, but I couldn't find any information about it.
Does anyone know anything about it, what it means, and what to do if it fails, like this one?

Hi Kirill,

This check is related to the Rolling Upgrade initiative described in
IEP-132.
https://cwiki.apache.org/confluence/display/IGNITE/IEP-132+Rolling+Upgrade

The main idea is that Ignite should eventually support upgrading a cluster
node by node, without full cluster downtime. To make that possible, some
parts of the codebase must preserve compatibility between old and new nodes
in a mixed-version topology, especially communication/discovery messages,
management API DTOs, binary metadata/marshalling-related classes, and other
version-sensitive protocol structures.

The new Rolling Upgrade check is an early guardrail for that. It does not
run a full rolling-upgrade scenario. Instead, it detects whether a PR
touches Java classes that look compatibility-sensitive, currently classes
using the org.apache.ignite.internal.Order annotation. If such files are
changed, the check fails intentionally, adds the compatibility label, and
posts a warning comment asking reviewers to check rolling-upgrade
compatibility.

So, if it fails, it does not necessarily mean that the PR is wrong. It
means: “please pay extra attention; this change may affect wire/protocol
compatibility.”

Sincerely,

Dmitriy Pavlov
