public class PreComputedRecordsSourceConnector
extends org.apache.kafka.connect.source.SourceConnector

Simple source connector which produces limited number of pre-computed records. It's similar to SimpleSourceConnector, but adjusted for benchmarks so fixed amount of records is generated beforehand and only these pre-generated records are sent to the consumer.
