    renu kumari wil investigate option. Stakeholder want clear separation between 'client' and 'internal' interfaces. Although both need to be available for publication, just different target audiences. Preferred Internal interface pre-fix is /ncmpDmi
• Discuss adding CM-Handle for SDN-R (network Slicing) with Ahila P 
  • Proposal for SDN-R integration: SDN-R Feature for adding cm-handle
  • Toine Siebelink clarified that instead of Async flow steps 2&3 a 'temporary' sync option is available right now on DMI-Plugin. Toine wil mail specification links to Ahila
  • Steps 4 & 5 are also already developed and test in Jakarta using SDN-C. These might need to be tested in SND-R environment.
  • CPS teams prefers NOT to have a third option for adding CM Handles. Instead we agreed on the following possible evolution path:
    1. SDN-R use synchronous method delivered in release I, mentioned above (can be done now)
    2. SDN-R publishes event of the same schema and same topic as PNF. This release CPS  is delivering the relevant event based API in J which has already been investigated , see

  • Interface overview: https://docs.onap.org/projects/onap-cps/en/latest/architecture.html 
  • For 'passtrough' (bypassing cache)  CPS-E-05 can already support XML (using JSON wrapping)
  • Cache not yet enabled in NCMP (planned for Jakarta). CPS-Core can be used to store any data and 'cache' it but currently only support json payload for data
  • Dell would like CPS to also support XML payload on CPS-E-05,  CPS-E-02 and CPS-E-03 interfaces (probably does not apply to CPS-E-01 (TBC)
    • CPS-E-02 could easily be made to 'accept' XML format too 
    • CPS-E-03 would required an additional parameter? to request XML output
    • DMI interface might be affect to, needs further investigation
  • DB storage is de-coupled from REST input format (interfaces are using java map objects instead) Postgress solution uses json format internally but this is not related to/affected by payload format
  • Toine Siebelink  and Michael Pruss will schedule a follow up meeting next week
• Present findings on Horizontal Scaling by Lee Anjella Macabuhay  
  • Conclusion; CPS-NCMP can scale horizontally without code changes
  • Lee Anjella Macabuhay  will add some information on how to increase the DB connection pool size for 'vertical scaling of a singel instance. as it was observed the pool size became a bottleneck when more then 5 simultaneous requests were made.
  • as part of discussion future possibilities for domain based (manual) setup of groups of CPS instances were discussed. Sharding could be used to distribute cm-handles.
