    • 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

  • 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
      • 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:
