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. Many of you have already seen Kovacs' comparison of nosql stores. Just throw a SQL DBMS into the decision matrix. Consider how several might w…

HN discussionhttp://memcached.org/ used to be. I haven't done system architecture in about 2 years but when we were looking at in memory databases, it came down to Redis or Memcache. Depending on what you need your database for, there are some that perform better than others. You can check this site for comparisons: http://kkovacs.eu/cassandra-vs-mongodb-vs-couchdb-vs-redis

HN discussionOne thing I always do is try to scope a database for the problem.

HN discussionI 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…
