A live auction application was developed for the Couchbase Connect Conference to demonstrate the capabilities of Couchbase 3.0, focusing on real-time data consistency across different data centers using bidirectional replication (XDCR). The application was created with Node.js, Couchbase SDK 2.0, and Bootstrap, and was designed to be completed within four days to showcase the agility of development with Couchbase. It featured an auction spread over two web servers in Salt Lake City and London, maintaining data consistency at wirespeed using the new DCP protocol. User interaction was managed through session cookies and a RESTful API, allowing multiple users to participate in bidding with dynamic updates via jQuery AJAX polling. Administration tasks such as resetting and controlling auction states were executed using curl commands, though the application was hard-coded and lacked secure access, serving primarily as a proof of concept. The source code was made available on GitHub for public scrutiny, and the demonstration utilized c3.4xlarge instances on AWS with Couchbase Server 3.0 installed with default settings to achieve high performance.
