public class StressSource
extends AbstractPollableSource
implements Configurable, BatchSizeSupported

StressSource is an internal load-generating source implementation which is very useful for stress tests. It allows User to configure the size of Event payload, with empty headers. User can configure total number of events to be sent as well maximum number of Successful Events to be delivered. Useful for tests Example configuration for Agent a1

   a1.sources = stresssource-1
   a1.channels = memoryChannel-1
   a1.sources.stresssource-1.type = org.apache.flume.source.StressSource
   a1.sources.stresssource-1.size = 10240
   a1.sources.stresssource-1.maxTotalEvents = 1000000
   a1.sources.stresssource-1.channels = memoryChannel-1
 

See AbstractPollableSource.configure(Context) for configuration options.
