Events are the lifeline of WSO2 CEP/DAS. They not only process data as events, but also interact with external systems using events. Event is a unit of data, and an event stream is a sequence of events of a particular type. The type of events can be defined as an event stream definition. The following sections explain how to work with events in WSO2 CEP.
...
| Property | Description |
|---|---|
| Event Stream Name | Name of the event stream. |
| Event Stream Version | Version of the event stream. (Default value is 1.0.0.) |
| Event Stream Description | Description of the events stream. (This is optional.) |
| Event Stream Nick-Name | Nick-names of an event streams separated by commas. (This is optional.) |
| Stream Attributes | The data the event contains. Data is divided into the following three categories for maintenance and usability. Thus gives more meaningful structure when it comes to aspects of data. It is not mandatory to have all three sections. But there should be at least one section defined.Also irrespective of these sections, they will be treated the same at the Siddhi level.
Please note that Attribute names should be unique within each sections. |
