Moksha provides many ways to acquire data in an efficient manner.
Moksha can communicate with various message brokers, using the AMQP, STOMP, and/or 0mq protocols. It also provides a simple API for producing and consuming messages, as well as allowing widgets to subscribe to live message streams within the users web browser.
A flexible caching layer is available to all Moksha widgets and applications. This middleware is setup by TurboGears2, and trivializes the act of caching expensive operations.
Moksha also provides recipies for integrating with nginx & memcached.
Moksha provides a powerful Feed widget that automatically handles fetching, parsing, and caching arbitrary feeds in an efficient, scalable manner.
