CouchDB and Redis: Strengths and Weaknesses
Knowing the strenghts and weaknesses of each of them could help making a decision. But do not fall for comparing them:
I’ve compiled a simpler item-by-item comparison of CouchDB and Redis, and it appears to be that CouchDB is strong precisely where Redis is weak (storing large amounts of rarely-changing but heavily indexed data), and Redis is strong precisely where CouchDB is weak (storing moderate amounts of fast-changing data).
