What Hacker News says?

  1. Both solve entirely different classes of problem. There are functional overlaps for small problem domains, but as your infrastructure tries to do more, you may find a need to run several distinct lightweight services backed by a variety of datastores serving focused requests.

  7. One thing I always do is try to scope a database for the problem. This site[1] has been a valuable resource for myself and colleague who were evaluation the best way to store/access our data depending on what we need back. [1] - http://kkovacs.eu/cassandra-vs-mongodb-vs-couchdb-vs-redis

  17. I have a hard time keeping up with all the NoSQL engines out there. What can I do about it? I could easily evaluate, say, CouchDB in a side-project, but that's a) not necessarily going to tell me a lot about its characteristics at scale, and b) I can't do this even for the big NoSQL engines out there. Is there a good overview? I realize that this is sort of an oxymoron -- a high level overview is doomed to fail beca…
