Server / Cluster version information

[MikeGoldsmith]

It would be desirable for the client to be able to know the Couchbase server version of the nodes it is connected to. This would be useful for determining if a particular feature is available or not. Also, consuming applications, projects could have additional requirements.

Cluster version information is available using the http://localhost:8091/pools/default. An example for parsing the response can be seen here.

Considerations:

• Minimum compatibility cluster version
• Per node server version
• Caching behaviour (default time + ability to override / force refresh)
• Version information (major, minor, patch, build and edition)

I think thats a great idea, and java has this already to varying degrees (i.e. we use it for test setup internally to figure out which tests to run). Other parts are exposed on the management APIs for retrieval purposes.

What could make sense is to collect the status quo for our SDKs and see what we currently have (and in parallel of course define where we want to be :)) 👍

[MikeGoldsmith]

Yeah, agree we should use what the SDKs already have implemented and see if it fits all of use-cases. I'll make a start on the RFC to find out what we already have.
