Couchbase is hosting a live webcast titled "New Year, New UI" on January 18th to showcase the refreshed user interface of Couchbase Capella, focusing on its developer experience enhancements. Participants can follow along using a free 30-day trial, which includes features like Single Sign-On (SSO) for authentication. The webcast will cover various aspects of the platform, such as setting up, exploring, and importing data, as well as connecting external applications by managing IP whitelists and access credentials. Attendees will gain insights into data tools, including the Query Workbench, key-value lookup, and full-text search options, while also learning about security measures and the new Magma storage engine for handling large datasets. The session promises interactive engagement with live Q&A and additional resources available on Couchbase forums and Discord for ongoing support.
