• Software Status

  • https://lf-onap.atlassian.net/browse/CPS-322 validation only required in Service-Layer. REst layer wil be handled using exception handling. Persistence Layer will depend on validation depend beforehand.

  • https://lf-onap.atlassian.net/browse/CPS-829 @Priyank Maheshwari and @Sourabh Sourabh are working together on this and with help of @Former user (Deleted) they can now test using Kafka docker image approach which is good enough for now. Any (future) Strimzi Kafka integration is Integration Team responsibility (Fiachra Corcoran) and onto for CPS team.

• Milestone M4 approved, next: RC, related tasks https://lf-onap.atlassian.net/browse/CPS-969

  • Some overlap with REQ-Owner related task handled by @Tony Finnerty 

• @Tony Finnerty and Team agreed on open issues presented by Dylan in CPS-877: Exclude any CM-Handles from queries/operations that are not in state 'READY'

  • https://lf-onap.atlassian.net/browse/CPS-977 has been created an added to workitem for R11 planning

  • @Lee Anjella Macabuhay  is on holidays next week and needs to wrap up  https://gerrit.onap.org/r/c/cps/+/128013 can merge with comments but not closing user story so someone else can take over next week,

  • Impact of https://lf-onap.atlassian.net/browse/CPS-961 agreed that xPath stored in DB is for 'internal use' only and not exposed to end-user. We can normalize storage for better compatibility and adherence to xpath conventions when retrieving it. @Lathishbabu Ganesan will work out prosed solution and do some PoC for this.

  • https://lf-onap.atlassian.net/browse/CPS-962 has been split of from CPS-960 will be handed over from @Joseph Keenan to @renu kumari when she has time (can be paused for now)

• Propose @Joseph Keenan to become committer for CPS-Core and DMI-Plugin

• A.O.B.

  • @Luke Gleeson (Unlicensed)  presented walkthrough and demo re. https://lf-onap.atlassian.net/browse/CPS-911

    • @Aditya Puthuparambil CPS-847 no need for 3 variations of operations in CSIT test. Issue with deployment of CPS_Temporal related to bguf @Former user (Deleted) is working on. Aditya and Bruno will work together to resolve. Team test strategy needs to consider 'component/black-box testing' @Toine Siebelink will call meeting to follow that up.

    • @renu kumari discussed proposal WIP: CPS-896: CMHandle Registration Response structure with team

      • Order for processing can be improved to: delete->create→update

      • No special requirements/validation of multiple same-operations on one cm handle (e.g 2nd create will fail, 2nd update will override previous)

      • Delete of node registered by other plugin,  @Toine Siebelink  will check with @Tony Finnerty 

      • Exact structure of response, team prefer format with status for each node so successful updates could (later) be included too. @Toine Siebelink wil check with stakeholders

• Jakarta Release update: Release Planning: Jakarta

  • Code freeze moved to March 10

• Software Status

  • https://lf-onap.atlassian.net/browse/CPS-856 retry mechanism parameters still a bit unclear. Not working with unit test. Might need follow up discussion with Stakeholder and @Former user (Deleted) too

• @Joseph Keenan will demo API Updates (https://lf-onap.atlassian.net/browse/CPS-822 & https://lf-onap.atlassian.net/browse/CPS-823)

• @Sourabh Sourabh will demo logging control (documentation) https://lf-onap.atlassian.net/browse/CPS-604

  • @renu kumari  observed logging management require no authorization but could impacts system! Only accessible from inside cluster which is good enough for now.

• @Dylan Byrne will present CPS-817: Create Endpoint for Get Cm Handle Details

• @Sourabh Sourabh will demo https://lf-onap.atlassian.net/browse/CPS-855

  • The logging demonstrated is only to be turned on for specific functional tets to determine time spent during functional execution. Load test wil be affected too much by this.

  • Logging (configuration) guidelines will be documented as part of https://lf-onap.atlassian.net/browse/CPS-604

  • The logging introduced here probably needs re-start of service as it is enable using an annotation. We'll await client-feedback to see if this suffices.

• @Lee Anjella Macabuhay  will demo (initial findings) https://lf-onap.atlassian.net/browse/CPS-802

  • 'restconf' responses are somewhat smaller then equivalent 'rests' responses. This needs some further investigation. CSIT test using the new version of SDN-C will determine if there are significant issues but this is not expected

  • Some small changes were seen comparing legacy (SDNC 1.8) output with current output on the 'rests' interface. But these could be related to small model and data instance updates that have been part of the new SDN-C Deployment

• Follow up E2E Slicing use-case impacts with @Niranjana Y (now limited to https://lf-onap.atlassian.net/browse/CPS-461)

  • Niranjana has prepared CPS-TBDMT Output transformation and existing template update. Required change are well understood but are dependent on CPS delivering https://lf-onap.atlassian.net/browse/CPS-865

  • Niranjana point out an 'additional prefix ' in the output from SDN-C (using NCMP passthrough). https://lf-onap.atlassian.net/browse/CPS-870 has been created to track and address this issue

• ONAP Best practice related work items: Jakarta Impact View per Component

  • https://lf-onap.atlassian.net/browse/CPS-869 has been created to address logging details adherence to ONAP requirements

• Discuss E2E Slicing usecase impacts on CPS with @Ahila P CPS-NCMP APIs Support for E2E Network Slicing use case

  • Cached data not (yet) available through CPS-E-05 (ref. to CPS-NCMP ↔ DMI-Plugin Interface Details Jakarta-R10)

  • Initial cache will be read-only, datastores:operational. For NMDA datastore model refer to https://datatracker.ietf.org/doc/html/rfc8342

  • CPS team will work on datastores:operational cache during Jakarta

  • @Toine Siebelink  has added a new work item (#15 on R10 release plan) to allow update of cache when SDN-R updates corresponding device data through a messaging based solution)

  • E2E Slicing team will continue to write using SND-R during Jakarta and work with CSP team to fully cached solution in next release (Kohn)

  • CPS team wil meet again with @Ahila P to follow up and clarify Jakarta scope

• @Luke Gleeson (Unlicensed) presented proposal: CPS-461 Align DataNode for Get and Post/Put endpoints in CPS Core

  • This will have some impacts on TBDMT process of data.

  • suggested to update template to handle required transformation to original data format (get child from parent)0 CPS Team can help out with these impacts to speed up changes. @Ahila P will consider and revert to @Toine Siebelink and @Luke Gleeson (Unlicensed)

  • query interface methods required for m-handle state, sync-state etc. Agreed to handle this in follow up spike

  • transition from Ready to Locked is possible (add to diagram)

  • update state transition diagram with descriptions (scenarios) of each possible transition 

• confirm Test Integration Lead: @Aditya Puthuparambil  will continue this role for Jakarta release

Happy New Year!

• Discuss Dell requirement for XML Payload with @Michael Pruss 

  • 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.

  • @kieran mccarthy  confirm spike goal was achieved and wil contact Peter Turcsany for follow up load testing. 

• Software Status 

  • nothing of special interest

  • Demo of pass-through delete use case.

    • https://lf-onap.atlassian.net/browse/CPS-797 symptoms now seem to occur consistently, time to investigate this bug!

  • proposed Yang model for the public additional properties feature: CPS-677 Support 'public' Cm Handle Properties

    • @kieran mccarthy agreed to the name 'public-properties' (without 'additional')

  • Liquibase development steps: DB Schema Changes (Liquibase Change Logs)

    • Ready for review!

• @Niranjana Y  asked about backward incompatible changes in CPS-Core or CPS-NCMP. @Toine Siebelink  pointed out changes being proposed here: https://lf-onap.atlassian.net/wiki/display/DW/CPS+Exceptions+and+REST+APIs+HTTP+Response+Codes#CPSExceptionsandRESTAPIsHTTPResponseCodes-SpikeCPS-728:InventoryofHTTPResponseCodesforallCPSinterfaces Does not current affect  TBDMT

• Michael Pruss (Dell) explained his team is interested in using CPS but with support for XML data. He offered that his team can contribute to CPS to realize this in Jakarta. We agrred to start mail exchange next week and probably a first meeting in januari to understand the requirements more clearly...

• Holiday Schedule: no more weekly meeting until Jan 7th!
