debug |
true or false (default is false) |
Enables detailed tracing on this batch data stream. |
EnablePerformanceMeasurement |
true or false (default is false) |
Calculates the total time spent in the batch data streams and the processRecord method, if you are using the GenericXDBatchStep. |
EnableDetailedPerformanceMeasurement |
true or false (default is false) |
