Critical Description
A few suggestion on making the log files easier to read and grep:
All messages should be pre fixed with the bucket they are related to. This is extremely important when a user has a number of different couchbase buckets connecting to different clusters but all logging to one place.
When the client starts for the 1st time it should log its own version.
What did the state change from and to?
Connection state changed for sun.nio.ch.SelectionKeyImpl@51ec8098
What is Binary config (I assume carrier publication)?
Binary config not available, bootstrapped through HTTP.
