The Producer sends a message to the networkMapReloadQueue and the notificationsReloadQueue which causes the NetworkMap to be switched.

Within the attemptNetworkMapDatabaseRepopulation function, the following functions are called:

tarUnpacker.execute(); - net net.dante.dashboard.population.tar.TarUnpacker
opsDbImporter.importDump(); - net net.dante.dashboard.data.importAndExport.DatabaseImporter
