Operators and Schemas

You typically provide a schema definition in the property editor for the Stream Input operator, by providing an output schema name and one or more attribute name, data type and size information.

Many operators that follow the Stream Input Stream operator do not alter your schema definition, as these operators do not modify data or its format as it moves through the Intelligent Event Processing Module.

Exceptions to this rule include the following modifier operators:

Operators that follow any of these modifiers inherit their new output schema.

Windows, also known as sliding windows, enable you to conceive of a meaningful boundary on the event stream so you can query it effectively.
