updatePipe

Update an existing pipe. When you call UpdatePipe, EventBridge only the updates fields you have specified in the request; the rest remain unchanged. The exception to this is if you modify any Amazon Web Services-service specific fields in the SourceParameters, EnrichmentParameters, or TargetParameters objects. For example, DynamoDBStreamParameters or EventBridgeEventBusParameters. EventBridge updates the fields in these objects atomically as one and overrides existing values. This is by design, and means that if you don't specify an optional field in one of these Parameters objects, EventBridge sets that field to its system-default value during the update.
