A master Content Management Service maintains probabilistic model and classifier model data files across the domain. When you compile a probabilistic model or classifier model in the Developer tool, you update the model files on the master Content Management Service machine.

If a node in the domain runs a Content Management Service, the node stores local copies of the probabilistic model and classifier model files. The master Content Management Service synchronizes the probabilistic model and classifier model files on the domain nodes with the master Content Management Service files every 10 minutes.
