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

A very simple SourceConnector for testing that reliably produces the same records in the same order, and useful for testing the infrastructure to run SourceConnectors.

This connector produces messages with keys having a single monotonically-increasing integer field named id:

 {
     "id" : "1"
 }
 

and values with a batch field containing the 1-based batch number, a record field containing the 1-based record number within the batch, and an optional timestamp field that contains a simulated number of milliseconds past epoch computed by adding the start time of the connector task with the message id:

 {
     "batch" : "1",
     "record" : "1",
     "timestamp" : null
 }
