What is the Cajundome used for?

Can you tell me more about the Cajundome and what types of events it typically hosts? Is it a multipurpose venue that can cater to a wide range of activities, or does it specialize in a particular type of gathering? How does it contribute to the local community and economy? Are there any notable events that have taken place there in the past, and are there any upcoming events that people should be aware of?
