Sentinel: Data Synchronizer Process (Data Controller)

Explanation of the Data Synchronizer Process (Data Controller)

The Data Synchronizer (data_synchronizer) process manages the modification of configuration data by multiple users. When a user requests to modify data through the Sentinel Control Center, the data record is locked by the data_synchronizer. The details of who locked the data are published to the other active Sentinel Control Centers, and no other users may modify that data. If a Sentinel Control Center is closed before it unlocks any data that it has locked, the locks will timeout.
