Chihaya was designed with this in mind, but also tries to remain -independent. Chihaya connects to two data stores. The first, known as "cache", is used between -Chihaya processes in order to keep up with fast changing data. The second, known as "storage", -is your web application's data store. Changes immediately take place in the cache, which is why -fast data stores are recommended. These changes are also collected and periodically applied to the -storage in order to avoid locking up your web application's data store. +See [the wiki](https://github.com/pushrax/chihaya/wiki) for a discussion of the design behind Chihaya. +## Using Chihaya -## Installing +Chihaya is intended to work with existing torrent indexing web frameworks, such as [batter] and [Gazelle]. +Following the Unix way, it is built to perform a specific task, and interface with any system that +needs its functionality.
