With composite events, users are now able to create a new event composed of a combination of events and use it for analysis
A composite event is a new type of event that gives you more flexibility using events and properties. For example, you can create a composite event containing “Flight Booked” and “Hotel Booked” and then save it as “Travel Booked”. Now you can use “Travel Booked” just like a regular event. Then, any time a user books a flight or hotel they’ll be included in that event.
