Nomad inherited protocol version numbering configuration from Consul and Serf, but unlike those projects Nomad has never used it. Nomad's `protocol_version` has always been `1`. While the code is effectively unused and therefore poses no runtime risks to leave, I felt like removing it was best because: 1. Nomad's RPC subsystem has been able to evolve extensively without needing to increment the version number. 2. Nomad's HTTP API has evolved extensively without increment `API{Major,Minor}Version`. If we want to version the HTTP API in the future, I doubt this is the mechanism we would choose. 3. The presence of the `server.protocol_version` configuration parameter is confusing since `server.raft_protocol` *is* an important parameter for operators to consider. Even more confusing is that there is a distinct Serf protocol version which is included in `nomad server members` output under the heading `Protocol`. `raft_protocol` is the *only* protocol version relevant to Nomad developers and operators. The other protocol versions are either deadcode or have never changed (Serf). 4. If we were to need to version the RPC, HTTP API, or Serf protocols, I don't think these configuration parameters and variables are the best choice. If we come to that point we should choose a versioning scheme based on the use case and modern best practices -- not this 6+ year old dead code. |
