Manage status messages in CouchDB with MapReduce
On the Couch
Conclusions
This article has probably only whet your appetite for opportunities with CouchDB. MapReduce is a powerful paradigm for designing queries against large volumes of data, and it is particularly powerful when combined with grouping.
There are many other interesting topics related to CouchDB that I have not covered. In addition to attachments is the ability to attach binary data (e.g., images and other formats) to, and retrieve it from, a document. Also, Mango is the declarative CouchDB query language that allows data to be queried without MapReduce. Finally, the cluster and replication model with configurable shards and copies, among other things, is a strong argument for getting to know the database. I hope you have fun doing so!
