| * upgrades, when nodes may be running a mixture of versions, this service can be used to coordinate across those |
| * versions. But users of this service must be extremely careful to preserve backward/forward compatibility for |
| * messages sent across versions. Encoders and decoders used for messages sent/received on this service should |
| * support evolving schemas. |
