Distributed sampling allows two types of execution:

Automatically exports comma-separated side files (sampling.dat and method.rc) in the config subfolder of the Data Express extension installation path. It produces sampling results, and then imports those results into the client knowledge base.

This type of sampling requires no validation.

You can manually export the comma-separated side files, sample manually from the console, and then load your sampling results into the client knowledge base from the Distributed Sampler dialog box in Data Builder.

In this case, validation is useful to ensure that the data stores in the sampling results file match the exported sampling.dat file. This prevents errors and ensures consistent results.

Validation is performed when you specify a Sampling data file in the Distributed Sampler dialog box. See Load results from file for instructions.
