AVC Subscription, advance filter. Part 2 of cmhandles
It includes creating subscription with patternmatch cmhandles.

| Support for Async datajobs Not just for reading specific fdn, but rather QUERY Group of FDN , it's just a broadcast to every DMI plugin. The response should mimic sending a broadcast to 2 or more CM Handles CPS Team wil only do java interface. REST Interface is done in DCM | NEW interface aligning with 3GPP i.e FDN instead of CM-HandleIds (Read use case can re-use existing dataOperationz impl. after mapping FDNs to CMHandleIds for input and back for output!) Read, Create, Update, Delete and Action support. I.e for passthrough only * NCMP to introduce a qualifier to be used along with the DMI plugin so NCMP can break the request with multiple cmhandle into batches based on the DMI plugin and the Qualifier (where qualifier should be EMS name / id). |
