com.linkedin.databus.core.test.DbusEventGenerator.generateEvents()
Generate specified number of constant sized events. @param numEvents : Number of events desired @param windowSize : Max window size (transaction size) @param maxEventSize : maximum event size expected @param payloadSize : payload size in bytes @param useLastEventAsScn : if true, use count of last event of window as window scn; else use i/windowSize+1 @param eventVector : output container that is populated with the events @return last window number generated
