The Field Reducer Processor can be used when you need to remove fields from a GeoEvent. This effectively deletes attribute data from the GeoEvent being processed, allowing a simplified representation of the GeoEvent to be routed for additional processing or sent to an output. When configuring the Field Reducer Processor, specify the fields to be removed as a comma-separated list.
Field reduction alters the GeoEvent's schema, which requires GeoEvent Server to create a new GeoEvent Definition. The new GeoEvent Definition will be managed by GeoEvent Server and deleted if changes are made to the processor or the GeoEvent Service in which the processor participates. Lastly, specify a name for the new resulting GeoEvent Definition.
