The purpose of the SF Connector component is to fetch selected data form [url removed, login to view] and to prepare the flat text output (XML format) for indexing.
SF Connector is simple one way integration with [url removed, login to view] except the updating scenario. SF Connector works on top of exported data package. The definition of this data package and how often it is exported etc. is part of job fetching definition inside SF Connector configuration file.
