---------------------------------------
Assignee: Mikhail Petrov
> Add support for changing Distributed Attribute IDs in an RU-compatible way
> --------------------------------------------------------------------------
>
> Key: IGNITE-29029
> URL: https://issues.apache.org/jira/browse/IGNITE-29029
> Project: Ignite
> Issue Type: Task
> Reporter: Mikhail Petrov
> Assignee: Mikhail Petrov
> Priority: Major
>
> Currently, Distributed Attribute propagation relies on an attribute ID
> registry, which must contain the same set of distributed attributes on all
> cluster nodes. Otherwise, an attribute cannot be resolved by its ID.
> During a Rolling Upgrade, different cluster nodes may have registries
> containing different sets of distributed attributes. Therefore, we need to
> introduce a mechanism that takes the versions of the communicating nodes into
> account when propagating Distributed Attributes during an RU.
