Refer Config DB setup
Config DB is used to store the configuration and operation parameters of xNFs. It also persists the RAN slice details and acts as a RAN inventory.
For G-release, it stores the details of NearRTRIC, CU, DU, RRM Policy and RAN Slice details. Static mapping between tracking area and cells are also persisted.
