Both consumer-1 and consumer-2 are properties of source clusters mirror maker transfers data from. Mirror maker is designed to be able to consume data from N sources (N >= 1) and transfer data to one destination cluster. You are free to supply as many consumer properties as you want to instruct mirror maker where to consumer data from.
