      Description

      During unit test runs I noticed with the Java client that 2.1.0 exposes less key stats to the client than before. I dont know if this is a bug or needs to be properly documented, but either way.

      It got reduced from 7 to 5 and those 2 are missing:

      key_data_age
      key_last_modification_time

      I searched through the MB jira for those keys but didnt find the right thing.

      Thanks,
      Michael

        Woops, I guess "storage-engine" is not ep_engine. Please reassign as needed!

        Mike,

        Do you have any idea why we removed these two key stats?

        These two stats were removed as part of the meta-data reduction. Since we removed the dirtiness field we lost the ability to calculate these. Before I submitted this code I communicated all of the thing we would lose by removing this field with PM, support, and engineering and everyone at the time deemed this acceptable. Along with these key stats I believe we also lost a few other stats (paged_out _time, ep_too_young, ep_too_old, and others) too. If this is not documented I can work with the documentation team to get this added to the release notes.
