The Rest service is designed to act as a gateway into your Scrapy Cluster in order to provide services for requests and information that otherwise may not speak to Kafka. It provides a pass-through style interface, allowing the Kafka Monitor to handle the actual validation of the request.
The Rest service is one of the newer components to Scrapy Cluster, and provides the ability for a service to provide arbitrary JSON to be passed to the cluster, and to request information for longer jobs that traditionally time out during the execution of a call.
The ability for Scrapy Cluster to provide restful interaction opens up the door to User Interfaces, http/https requests, and generally more usability of the system. Built upon a simple Flask framework, the Rest service provides a foundation for Restful Kafka interaction and with Scrapy Cluster.
