Jazoon is a popular conference in Zurich that attracts a large number of Java developers, with around 500+ attendees for one talk. The event features multiple tracks and a unique venue, which can be an unusual setting for speakers to present. The understanding level among attendees varies widely, with some having experience with NoSQL databases like Couchbase or CouchDB. The conference covers a range of topics related to using Couchbase with the Java SDK, including document design and incremental map-reduce based views. Despite covering some internal details during demonstrations, there was still confusion about similarities and distinctions between Couchbase and CouchDB. However, the overall sentiment from attendees suggests a high interest in adopting NoSQL technologies and Couchbase for change in their business approaches.
