Mikhail Petrov updated IGNITE-29029:
------------------------------------
Description:
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.
> Add support for changing Distributed Attribute IDs in an RU-compatible way
