> Support relaying unknown message fields when resending messages
> ---------------------------------------------------------------
>
> Key: IGNITE-29079
> URL: https://issues.apache.org/jira/browse/IGNITE-29079
> Project: Ignite
> Issue Type: Task
> Reporter: Mikhail Petrov
> Assignee: Mikhail Petrov
> Priority: Major
> Time Spent: 2h 50m
> Remaining Estimate: 0h
>
> The direct message format is positional. The serializer writes fields in
> @Order sequence without storing per-field names or lengths. IGNITE-28851 made
> a pair of mixed-version nodes agree on the same list of fields to be
> transmitted. All fields must be known to the receiver, which must also be
> able to deserialize them.
> This rule has a consequence for the Discovery ring: a field introduced in
> version V is lost when a message travels through a V → V-1 → V path. In a
> ring, this can occur on a path such as new → old → ... → old → new.
> We need to support relaying a field introduced under feature F across the
> entire new → old → ... → old → new path, even when the intermediate old nodes
> do not have feature F and cannot deserialize the field value.
