Over the years, Mozilla has shifted to using Taskcluster as its primary continuous integration system. Communication becomes essential between the various components when scaling the infrastructure. Mozilla uses Pulse to enable an exchange of information Mozilla’s systems. Pulse is actually a RabbitMQ server which uses AMQP ( and follows a Publish--Subscribe pattern). Taskcluster-events is a service that allows web clients to listen for pulse messages without RabbitMQ credentials and without the need for a TCP connection to the RabbitMQ server. However, currently, taskcluster-events is old and poorly designed, without protocol specification. This proposal aims to completely rebuild taskcluster-events from scratch, ensuring it is robust and free of major bugs / failures.
