To create a Complex Event Processor (CEP) Project, open the Developer Studio Dashboard, and then scroll down and click CEP Project.
You can choose to create a new, empty CEP project or import an existing one by specifying a CEP configuration XML file. When you click Finish, the CEP Editor appears, where you can work in the Design view or the Source view to configure the CEP bucket, including the engine configuration properties (properties that control distributed deployment), inputs, and queries.
After you have configured the bucket, click the Source tab and validate the configuration. If the queryEventType property is set to Map, change it to Tuple if you are using Siddhi.
You can now export the generated bucket.xml file as a CAR file using a Composite Application Project. For more information see Packaging Artifacts as C-App Archive in the CEP documentation.
