Storing data to CouchDB with Cradle
In order to achieve stellar performance speeds, MongoDB has a relaxed view towards Atomicity Consistency Isolation Durability (ACID) compliance. However, this means there is a (slight) chance that data can become corrupt (especially if there was a power cut in the middle of an operation). CouchDB, on the other hand, is ACID compliant to the extent that when replicated and synchronized, data eventually becomes consistent. Therefore, while slower than MongoDB, it has the added reliability advantage.
CouchDB is entirely administrated via HTTP REST calls, so we could do all of our work with CouchDB using http.request
. Nevertheless, we can use Cradle to interact with CouchDB in an easy, high-level way, along with the added speed enhancement of automated caching.
In this recipe, we'll use Cradle to store the famous quotes to CouchDB.
Getting ready
We'll need to install and run CouchDB. For this, head on over to http://wiki.apache.org/couchdb/Installation for instructions...
