Description

This feature proposes to add asynchronous methods for MongoDB client which lives in common module. Currently, MongoDB client is used by all modules and they are synchronous. By the help of this feature, database operations are performed more efficiently.

Demo or definition of done

• Call the asynchronous methods from common module to perform MongoDB operations in other OSM modules (RO, LCM, N2VC ..)

This work is considered done when all the implementations, tests and documentation is contributed to use this feature.
