Comparitive experience with SAP Hana

Hello, Couchbase Community!
I’m interested in some product feedback relative to SAP Hana and I have got the following questions:

  1. If you have used Hana, what are your impressions of it as a NoSQL database?
  2. Are there that Couchbase might consider as future product enhancements?
  3. Are there any patterns, data models, or use cases in your opinion for which either Couchbase or Hana is clearly “better” or “worse”?

You can reply directly in this thread (or you can privately send me a chat message if that works better).

I look forward to your feedback!
