|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 |
| Data Write/Read Performance | See also CPS-Core Read & Write (large load) Test Results from Wipro/Fujitsu See Montreal Read/Write Performance for latest performance results (23/08) |
| ||||||||||||||||||||||||||||||||||||||||||||
| 2 |
|
| Implementing Data Notifications & Subscription Notifications on a US by US basis Scope Add: What kind of access controls are required on topics? Spike is required for this. Work Item created (23/05). | Notifications
Subscriptions
| ||||||||||||||||||||||||||||||||||||||||||||
| 3 |
| Support update of cached data through a message driven solution. Respond to VES Events from Devices in ONAP | Receive VES Event and transform it into a 'standard DMI→NCMP events (schema owned by NCMP) |
| ||||||||||||||||||||||||||||||||||||||||||||
| 4 |
| Batch ( | Allow batch operations for NCMP REST and CPS-Core Java Interfaces. All new events will comply to cloudevents.
|
| ||||||||||||||||||||||||||||||||||||||||||||
| 5 |
| CM Handle Connectivity Freshness/Staleness | Need to model what staleness is (current CPS only has concept of model-sync state, nothing about connectivity) |
| ||||||||||||||||||||||||||||||||||||||||||||
| 6 |
| Update YANG schema-set for CM handle using ModuleSetTag |
|
| ||||||||||||||||||||||||||||||||||||||||||||
| 7 |
| Merge CM data subscriptions in NCMP when forwarding it to DMI |
| |||||||||||||||||||||||||||||||||||||||||||||
| 8 |
| Event Digest | Additional field to help clients filter CM AVC Events (S) | |||||||||||||||||||||||||||||||||||||||||||||
| 9 |
| AVC Subscription, advance filter | Filter on 'Type' instead of list of CM Handle IDs → 'Type' could be defined as the yang module set containing a specific module (name and version) (S) | |||||||||||||||||||||||||||||||||||||||||||||
| 10 |
| Support for list as top level data node |
| |||||||||||||||||||||||||||||||||||||||||||||
| 11 |
| CPS & NCMP Feature Enhancement for M Release |
| |||||||||||||||||||||||||||||||||||||||||||||
| 12 |
| Spike for documenting Kafka interfaces using AsyncAPI | - Documentation Generation - Code Generation (contract first, stubs) | |||||||||||||||||||||||||||||||||||||||||||||
| 13 |
| Refactor legacy NCMP ASync Response Events to use Cloud Events format | (M) |
| ||||||||||||||||||||||||||||||||||||||||||||
| 14 | TBC | Support NCMP-CPS upgrade | Currently only custom upgrade is supported. (upon request) Requirement: It shall be possible to upgrade NCMP-CPS from release N-1 to N (without requiring manual intervention/workarounds). N is defined as any release requested by ESH
Technical Debt to be addressed: Liquibase is used in CPS to manage data(upgrades) in CPS Study: Resolve technical debt (mixed data). NCMP Data upgrade. CPS Core need to support model upgrade so that NCMP can use it, |
| ||||||||||||||||||||||||||||||||||||||||||||
| 15 | TBC | Support multiple identifiers (alternatives for CM Handle ID) | (M) - Not sure. Scope not known yet. | |||||||||||||||||||||||||||||||||||||||||||||
| 16 | Access control for topics which are created by NCMP . | Spike needs to be conducted. | ||||||||||||||||||||||||||||||||||||||||||||||
| 17 | Invoke YANG modelled action | Always on operational datastore. Supported for nmcp:passthrough-operational and if executed against ncmp:operational then it is always forwarded to dmi plugin. Is there another story for forwarding to be included as a dependency? Always run as async request. Is this dependent on CPS-1127 - see spin-off user stories table below this on. KMC : Can we deprioritize - this can be run against passthrough-operational for now. Just have to agree on the API / URL for the action to progress at this stage so that the passthrough-operational form is aligned with final operational form. | ||||||||||||||||||||||||||||||||||||||||||||||
| 18 | Enhanced query support (fields) | Currently the passthrough has an 'fields' parameter to do a scoped query. Propose to support this in non-passthrough so it is promoted to a fully supported option, e.g. {ncmp-root}/ncmp/v1/ch/335ff/data/ds/ncmp-datastore:passthrough-operational? KMC : Do we support restconf like queries or xpath only? (L) . | ||||||||||||||||||||||||||||||||||||||||||||||
| 19 | Enhanced query support (scope) | Currently the passthrough has an 'fields' parameter to do a scoped query. KMC : Do we support restconf like queries or xpath only? (L) | ||||||||||||||||||||||||||||||||||||||||||||||
| 20 | TBC | Support ncmp-datastores:running for reading data (single CM handle, synchronous only) | See CPS-391 page for details about supported operations and combinations. Note: There can be some overlap between work items for #5, #6, #11 and #12. Read from operations. (S) - Forward only. No validation or data enhancements (add prefixis) | |||||||||||||||||||||||||||||||||||||||||||||
| 21 | TBC | Support ncmp-datastores:running for writing data (single CM handle, synchronous only) | (S) As per #18 | |||||||||||||||||||||||||||||||||||||||||||||
| 22 | TBC | Support relationships for 'Instance Identifier' | Should be possible to identify a cmhandle using multiple instance identifiers. (M) - Not sure. Scope not known yet. |
| ||||||||||||||||||||||||||||||||||||||||||||
| 23 | Retrieve single module resource | /v1/ch/{cm-handle}/modules/definitions/{moduleName} (S) | ||||||||||||||||||||||||||||||||||||||||||||||
| 24 | Access control for public interfaces (NCMP, CPS-Core, DMI?) | KMC : What level of access control is there today - both on CPS and NCMP interfaces? | ||||||||||||||||||||||||||||||||||||||||||||||
| 25 | Fine-grained cache configuration | |||||||||||||||||||||||||||||||||||||||||||||||
| 26 | Support for HTTPS and authentication
| Validation required whether this is still needed. |
| |||||||||||||||||||||||||||||||||||||||||||||
| 27 | TBC | Send notifications on write operation in ncmp-datastores:running for (single CM handle, synchronous only) | ||||||||||||||||||||||||||||||||||||||||||||||
| 28 | schema-set update for CM handle with cached data present | Need to address case with incompatible model changes. Scope: Upgrade of model that is cached? Lee Anjella to confirm. | ||||||||||||||||||||||||||||||||||||||||||||||
| 29 | Invoke YANG modelled RPC | Specification required. Rebbot/Reset type of actions on node. | ||||||||||||||||||||||||||||||||||||||||||||||
| 30 |
| CM data subscriptions from application to DMI [Part 2] | This epic was created to take on additional scope which got added to |

Longer term roadmap
- CPS-Core will have extended query capabilities based on XPath expression.
- CPS-Core will enforce and control ownership of data it holds
- NCMP will be to able to 'detect' and sync xNF in the network
- Fine-cache cache control will determine what get cache for what xNF
- NCMP will support the query capabilities as CPS-Core and be extend with options similar to RESTConf's 'fields' and 'depth'

Testing and Integration Plans
- CPS has high level of built jUnit test (>97 on all components) which is enforced by our maven build scripts
- CPS has built in Persistence Layer test ie. test that integrate with real DB instance covering all use cases and are part of WoW
- CIST tests are part of CPS -Repo, see https://gerrit.onap.org/r/gitweb?p=cps.git;a=tree;f=csit;h=8505b66089f62b6431c1091edf820cbdbf4363d4;hb=HEAD
And executed automatically through the cps-review-verification-maven-master CI Job - E2E Integration with ONAP components was introduced in I-release and is now included in aforementioned CIST tests
