The guys from ☞ Couchio started to publish a series of CouchDB case studies. This is a very good initiative that is on par with myNoSQL intentions. Unfortunately, the three published so far — you can be read them ☞ here — are in my opinion too thin in technical details. Here is a short list of questions that I’d love to hear more about:
Why and how have you got to CouchDB?
Have you had to migrate existing data? How did you do that? Are you still using a relational or other storage solution?
What kind of replication strategy are you using?
Are you sharding you data? If yes, what strategy/solution are you using?
What lessons have you learned while using CouchDB?
If you can help me get these answer I bet it would make these CouchDB case studies even more interesting for the NoSQL community.
