Contest Data Server

The Contest Data Server (CDS) is a server that allows secure, authenticated HTTP connections to contest data. It provides REST endpoints for accessing a variety of contest-related services, allowing clients to access those services via standard HTTP requests.

Why would I need a CDS when I already have a Contest Control System (CCS)? The CDS:

• Supports a wider set of contest data, including webcam and desktop streams, recording reaction videos, and more
• Reduces load on CCS - let the CCS focus on teams and the CDS can handle external load
• Allows you to control multiple presentation clients through a single interface
• Implements the ICPC data access policy so every user only sees the contest data they're meant to

The CDS can be run as a standalone application or via a container image.
