• @Lukasz Rajewski Discuss use of cpsPath for get operations (instead of absolute xpath support only)

  • @Toine Siebelink explain the core reasons for NOT combining these 

    • Architecture design to separate 'get' from 'query' functionality: Client should be aware what they use when

    • Although xPath and cpsPath can look very similar the cost and complexity of processing a cpsPath is order of magnitude higher

    • xpath cannot easily be distinguished from  valid cpsPath unless the model is parsed too which again would lead to additional cost to support both on the same interface. 

    • Operation that modify the data will only support xPath too. This is again an architecture decision that is based on best practice, scalability and transparency.  If the get operations would support cpsPath the same would be expected for the operations that modify data too and would violate the aforementioned principles.

• @Lukasz Rajewski  asked about CPS → CPS Temporal notifications , performance effects

  • Delta interesting but prefer to use dataspace/datatores in future for this instead of CPS Temporal

  • Support with disabling notifications dataspace, details to be forwarded to @arne.chrestin 

• @Ahila P write operations performance was not prioritized in London release instead the focus was on read operations and some queries.  In Montreal we wil shift toward optimizing write operations too. But the team is short on resources and have a large backlog. @David Terwilliger  will try to get additional resourcing for the CPS team.  Ahila will create requirement Jira for optimizing write operations. 

• @Ahila P Pagination wil be progressed by DT/Tech Mahindra (also need tracking JIra for R13/Montreal)

• SoftwareStatus

  • London Branches have been created for CPS Repos, teams can start working on Montreal (master branch)  

  • CPS-1582 and CPS-1580 need to be dropped back to London

• @rajesh.bumca present study on pagination (https://wiki.onap.org/display/DW/CPS-1567%3A+Investigate+Implementation+of+pagination+for+Query+AP

  • Pagination of fragments not feasible as it stil needs to be recombined into a complete tree

  • Pagination by anchor seems feasible but wil only be usable for bulk operations

• SoftwareStatus

  •  

    • https://lf-onap.atlassian.net/browse/CPS-1568 @Toine Siebelink discussed this with @Tony Finnerty  and agreed CPS should be abel to handle DB down and have a retry mechanism too. So apart from ETH making deployment changes CPS team should also provide a build in robustness on DB connection...

    • @Halil Cakal and @Priyank Maheshwari are build new release for CPS, will try to incorporate this bugfix too: https://lf-onap.atlassian.net/browse/CPS-1563

• Milestone Status

  • CPS TEam completed all M3 tasks. Code free might start tomorrow, decision will be taken during TSC meeting!

• A.O.B

  • @RAVITEJA KARUMURI (EST) propose small improvement regarding docker log handling after CSIT test

    • Logs truncated because of print-buffer limitation

    • just affected local run

    • increase buffer size as workaround; @RAVITEJA KARUMURI (EST) will document

• Introducing Anirban Bhattacharjee Product Owner for CPS

• CI (docs) Build issue status

  • Ongoing CI Team aware troubleshooting ongoing

  • CPS Team can IGNORE this (new) job for now as long as all other jobs pass any Comitter can delete the -1 from CI Build and set Verify to +1 instead if need to merge pending commits

• SoftwareStatus

  • https://lf-onap.atlassian.net/browse/CPS-1497 Discussed model proposal with team and recorded  in Jira description

• @Luke Gleeson (Unlicensed) demo the forwarding of subscription create events to DMI Plugins https://lf-onap.atlassian.net/browse/CPS-1431

  • Happy flow looks good

  • Kafka configured to create non-existing topic on the fly so could not demo required behavior as per AC

  • Need update to handle non-existing cm-handles (possible  separate commit)

  • user story wil be demoed again when all negative scenarios are covered too

• @Vishal Varvate update on VES Event handling by NCMP

  • Events using Strimzi/Kafka instead on DMaaP (agreed)

  • Contact @Priyank Maheshwari re impl. Details regarding topics etc.

  • Simulator Changes ready

  • Need to agree mapping still. @Priyank Maheshwari  to call meeting to discuss

  • Need to agree scope for London / Montreal. @Priyank Maheshwari to call meeting to discuss

• @arne.chrestin & @Lukasz Rajewski proposed some new functionality 

  • Consider alternate database, mix and match possible?

    • database (technology) separated by dataspace (need a master dataspace to store the meta info)

    • @Lukasz Rajewski to work internally to share in follow-up meeting. 

  • Pagination, difficult for hierarchical data. AA&I has implemented something similar

    • Offload pagination to DB so it can be implemented in RI interface and support 

    • Consider https://www.postgresql.org/docs/current/queries-with.html#QUERIES-WITH-RECURSIVE

    • Plugin-interface 'optionally' support pagination

  • Large Datasets  performance, Ongoing @Ahila P has provide some test here, see CPS-Core Read & Write (large load) Test Results.

  • Scalability, has been test CPS Core and scale using multiple instances but quickly DB (Postgess becomes bottleneck) CPS current focus on optimizing code to get maximum out of singel CPS instances. There is scope here and good improvements are already seen.

• @Arpit Singh will present study: Support CPS Core Patch operation for multiple data nodes

  1. Two top element trees, patch using xpath /, error reported. Although support would be 'nice' there is no urgency. Need to check with DT stakeholder re. priority

  2. Two top elements but no children just leafs, works partially (only one tree would be updated,a s expected).  Expecting such simple model is unlikely and fixing 1. above should fix this too 

  3. List example problem is unclear, needs to be updated. It seems unrelated to multiple root scenario and possible legacy issue(bug). @Arpit Singh will separate this into a bug on its own. 

• SoftwareStatus

• @Rudrangi Anupriya presented on some early suggestion for supporting 'contains' operations, see CPS-1272 Support for contains in cps-path

  • Anupryia will expand example in a table to make it more clear. 

  • Before any further investigation Postgress JsonB query support for this should be investigated

• Backlog Grooming (only develop team present, took the opportunity to groom some upcoming stories)

  • https://lf-onap.atlassian.net/browse/CPS-1443 handed over to @Andras Zoltan Kiss from @Levente Csanyi 

  • https://lf-onap.atlassian.net/browse/CPS-1394 assigned to @Sourabh Sourabh 

• @Sourabh Sourabh  and @Daniel Hanrahan  presented delete Performance, preliminary results

  • See NCMP De-Register API Performance 

    • Native Query 10-20x improvement but not meeting requirement

    • Delete performance not linear: more nodes slower

    • Tested up to about 2,300 cm handles which is the highest feasible given the current performance

  • Delete-by-batch is in progress and it is hope that will give the required boost. Hopefully can be demonstrated/reported next week
