Low Volume Sources for Data Domain Discovery

Low volume sources contain up to 100,000 rows. The Profiling Service Module does not differentiate between flat file and relational sources. The Profiling Service Module uses a mapping strategy that runs a profile on up to 20 columns against 50 domains for each mapping.

Consider the following hardware considerations for low volume sources:

Component	Requirements
CPU	The CPU utilization is low. Additional CPU cores increase performance because the Profiling Service Module uses the multithreaded environment of the Data Integration Service.
Memory for Mapping	The low volume mapping uses approximately 128 MB without considering the data domain rules. The transformations in the data domain rules might require additional memory.
Disk	The Profiling Service Module does not generate intermediate results when you run data domain discovery for low volume sources. The disk requirement is negligible. However, the transformations in the data domain rules might require some amount of temporary disk.
