At run time, the cleanse engine evaluates the number of records to be cleansed. If only one (1) record is sent for cleansing, then the web service is invoked for that single record. If multiple records are to be cleansed, then the Process Server will batch a set of records together and pass that batch to the web service. This reduces latency on the web service call and results in better performance.

The maximum number of records included in a batch is determined by a parameter in the cmxcleanse.properties file:

The default value for that parameter is 50.
