I have been interested in using mongo as a logging system for Ircster for a while now (it supports large sets of data with full text search and very fast queries), however until recently there was no reasonable driver for node. There are now two drivers available node-mongodb (bindings to the C driver) and node-mongodb-native (a JS implementation of the driver). The native driver especially interests me as I can more easily understand and work with the code.

Redis is an extremely fast key-value pair database (a hash table basically) that also includes fast, atomic set and list operations. I’m planning to use it as part of my group software project at uni, the project requires us to handle large amounts of data with a large number of requests per second, which makes 110,000 writes per second (one of the features of Redis) very appealing.
