I'm confused as to why the solution described won't work with segment replication. As I understand it what that solution describes would be some writer nodes writing segments with *old* version while replicas' (readers) software gets upgraded. Since replicas *only read* they can continue to read these old (version N-1) index segments. Even if you wanted to allow them to do merging (why, I don't know) you could and they would write new-format segments, which is fine as long as they never share them with other replicas. Then once all replicas are on version N, you can upgrade the writer nodes to version N and start publishing version N segments. Where is the hitch - what am I missing? -- This is an automated message from the Apache Git Service.
