debug |
true or false (default is false) |
Enables detailed tracing on this batch datastream. |
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) |
Provides a more detailed breakdown of time spent in each method of the batch data-streams. |
file.encoding |
Encoding of the file. |
For example, CP1047 |
