Event Generator

Description

Generates events user-defined frequency.

There are two primary use cases for this component:

• Generating a stream of data (typically for testing): The #input variable, available downstream, will be populated with the data generated by this component. Use functions from the #RANDOM function group to produce random values.
• Periodically generating a trigger event: This enables your scenario to run periodically, unlocking additional use cases beyond the traditional stream processing.

Parameters and configuration

Name	Description
Schedule	Specifies how often events will be sent
Value	Expression specifying data payload that event will contain. Expression will be evaluated for every generated event

Advanced parameters

Name	Description
Count	Number of events that will be generated at every run
Event time	Expression which evaluates to the time when the event was created.
Max out-of-orderness	The maximum amount of time the event is allowed to be late before being ignored when computing the result for time-based stream transformations: aggregates in time windows and joins. To read more about this mechanism see Flink documentation
