We need a caching solution that essentially caches data (text files) anywhere from 3 days up to a week based on user preferences and criteria. In this case memory based caching does not make sense to us. We were referred to MemcacheDB however I also thought of some NO SQL solutions.
Our current application uses RDMS (MYSQL) and I guess it makes sense to use MemcacheDB however NOSQL does appeal as it is something more on the horizon. However we have not deployed a production level application under NOSQL and the beta stuff does not settle well with management/investors. Any how what are your thoughts and how would you address it?
Thank You
CouchDB and MongoDB are both great databases, but they are terrible choices for a cache layer on top of your existing RDBMS. Besides the fact that they are still fairly immature, they don’t suit the purpose at all. Also, speed-wise you’d be better off going without a cache layer than using CouchDB or MongoDB–they are both slower for simple read/writes than even MySQL. Yes, the NoSQL databases are “cool”, but that does not mean you should use them for something they were not meant to do.
I’d go with Memcached, as it’s just about the fastest and lightest thing you’ll find, and it’s well-known and well-supported.
