ChangeMachine

ChangeMachine was written to handle the CouchDB change processing required in Steelmesh. It is responsible for monitoring and responding to changes in a number of couchdb instances and taking appropriate actions in response to those changes.

The implementation of ChangeMachine is reasonably simple thanks to the flatiron neuron queueing library and through leveraging changemate notifiers.
