This page gives a description of CPS events including their fields Events will be split into events and Kafka headers Headers Issues & Decisions # Description Notes Decision 1 No Event properties defined for DMI AVC Event Priyank Maheshwari will need to specify and agreed event structure for DMI AVC Event with stakeholders ie. provide Jira ticket
Event Body should be compatible with RFC8641
kieran mccarthy has confirmed.
Priyank Maheshwari created JIRA to create the event body schema.
2 Bulk Operation events details have not yet be defined (just headers) Sourabh Sourabh to provide Jira tickets
Jira Legacyserver System Jira serverId 4733707d-2057-3a0f-ae5e-4fd8aff50176 key CPS-1658
3 Should all the events have same
kafka headers Headers kieran mccarthy 26 Apr 2023 Possibly Common (base) set of headers but mandatory aspect might differ. In practice we might need a separate headers (schema?) for each event
4 Clarify the format of the version eventSchemaVersion v1 or 1.0
EX ex : 1.0.0 (without 'v')
kieran mccarthy to check ORAN preference
kieran mccarthy confirms through email on 12 May 2023 to use semantic versioning which ORAN follows https://semver.org .
5 What to do with additional event headers (from DMI Plugins) kieran mccarthy 26 Apr 2023 if DMI produce additional headers NCMP will discard those i.e. not included in forwarded events
6 Event(Content) field in DMI Async Request Response Event has inconsistent name (compared with other schemas) Add V2 file Deprecate V1 Support both versions for a while Delete the V1 version (after some time) CPS Team 27 Apr 2023 Create a V2 of the schema and rename eventContent as event data
. Do it as part of the schema addition.
7 NCMP Async Request Response Event (#5) contains both an Event and ForwardedEvent ForwardedEvent is not wrapped inside Event but question now is if we need 2 events at all?!
Sourabh Sourabh and RAVITEJA KARUMURI (EST) can check how it is actually working and then we decide (create a JIRA ticket)
Wiki for the Study on NCMPAsyncRequestResponse event schema
Conclusion: events not designed as proposed, very inconsistent. Never go a bug because these async events aren't used at all (confirmed by Csaba Koscis) Instead bulk request wil be used for topology use cases.
10 May 2023 kieran mccarthy and team agreed to:
Temporary disable the legacy async request feature (task created: Jira Legacyserver System Jira serverId 4733707d-2057-3a0f-ae5e-4fd8aff50176 key CPS-1694
) As part of a lower priority work items (but during Montreal)
fix fiX related events with learnings from the new batch-usecase. (task created Jira Legacyserver System Jira serverId 4733707d-2057-3a0f-ae5e-4fd8aff50176 key CPS-1693
) 8 Dmi Data AVC Event, use of eventSource field Priyank Maheshwari wanted to store 'datastore' in this field but kieran mccarthy explained it to use for different purposes
kieran mccarthy Clients can use this field as per their requirements.
9 Can
Kafka Headers be described with 'schema's owned and managed by NCMP POC to follow. Jira Legacyserver System Jira serverId 4733707d-2057-3a0f-ae5e-4fd8aff50176 key CPS-1657
Defining header schema.
Integration of header with kafka.
Naming and versioning convention for the header schemas. 'id'
Does the headers schema have a version too?!
03 May 2023 Priyank Maheshwari confirmed headers can be described with a separate schema.
Both header schema's and event schemas will be published on https://docs.onap.org/projects/onap-cps/en/latest/cps-events.html
Header schema name and version will be maintained in the 'id' metadata field of header's schema .
10 Depending #10 can schema inherit/extend a common schema for common headers Commonly define them and then define what are mandatory(required) or optional as per the schema extending it.
If a field is not used in the extended schema then it should be able to handle it.
Extend extend the POC (on #9) to cover this.
09 May 2023 Priyank Maheshwari did the POC and the conclusion of that was that :-
One schema can extend the other schema. We cannot override the mandatory/optional parameter from the Parent schema. 09 May 2023 Toine Siebelink agrees to go ahead with separate schema/headers per event. There will be some duplication but it will have its advantage when versioning.
11 Is anyone using Async Request feature? See
Jira Legacyserver System Jira serverId 4733707d-2057-3a0f-ae5e-4fd8aff50176 key CPS-1660
we need to re-design event #4 (Covers Point 6 as well) and #5 in a backward incompatible way. If no-one is using this feature right now (suspected) we can do this more easily/cheaper! 03 May 2023 Csaba Kocsis confirmed this is not used by Ericsson currently. No plans to use soon for single-cmhandle requests either (TBC). Need to decide priority ( Csaba Kocsis to find out of
fixing fiXing the legacy schema(s) See decision on issue #7
12 Do we need additionalProperties for DMI ASync Data Request respondes (events #4, #5) The original code populates a framework defined 'additionalProperties' field with a singel key-value pair: "response-data",{<json data>}. No other (private) properties are added either in DMI PLugin or NCMP code. The name is just coincidence and misleading. In fact this 'additionalProperties' field should NOT have been used at all! No, the new schema should NOT add 'additionalProperties' field at all use 'additionalProperties:no' in the schema 13 AVC Subscription Event (DMI → NCMP) (events #3) Want to understand what 'data' is datatype referring to under Subscription Event? What value comes under 'schemaName' & 'SchemaVersion' of Datatype definition under AVC Subscription Event? Reconfirmation needed on 'schemaName' & 'SchemaVersion' should be in the payload?
In meeting 26 Apr 2023 kieran mccarthy updated #3 is ON HOLD to analyse further.
Agreed with Toine Siebelink on 18 May 2023 that Priyank Maheshwari will look into this from now as they are working on something related to this.
14 Align headers with CNCF Cloud Events Using standard headers as defined by Cloud Events and possibly common header extension See Table below, CNFC Cloud Event alignment CPS will use Cloud Events 3PP for all current and legacy events to ensure common format 23 May 2023 kieran mccarthy and Toine Siebelink agreed on general idea but exact list of common headers need to be agreed Jira (first impl.) to be added!
Jira Legacyserver System Jira serverId 4733707d-2057-3a0f-ae5e-4fd8aff50176 key CPS-1717
15 During the meeting we saw that the Kafka header fields were prefixed with " ce_ " so need to check if we are ok with that.
kieran mccarthy 07 Jun 2023 this issue is now no longer relevant as the decision was to use CNCF Cloud Events instead as per decision #14

15 During the meeting we saw that the Header fields were prefiXed with " ce_ " so we need to check if we are ok with that.
assume " ce_ " can be used as all user of the CNCF lib will get this behavior, will check if it can be replaced with no prefix at all. Sourabh Sourabh and Priyank Maheshwari concluded a cloud events specific serializer is used that add this prefix and cannot easily be changed (also that would be inconsistent use of this library)
CPS Team recommend to accept this prefix and simply document that this prefer is required when filtering on kafka headers defined by CloudEvenst standard.
07 Jun 2023 team agreed with kieran mccarthy to accept "ce_" prefix on serialzied CE defined headers. Note . Event(s) documentation in RTD should mentioned this clearly too
16 Do will still need/ can we
stil still use schemas for header details with CNCF library ?! How to publish info about non-standard headers like correlationid
? Meeting on 31 May 2023 Team agreed refer to CNFC doc. and add list of extensions in RTD documentation. (key and value constraints)
17
inconsistent Inconsistent casing convention for header fields v. json data fields Just observing. All header ion CNCF are lowercase whereas json field are camelCase. Don't
want to change but want to make sure agree... to be added to ALL events (declared mandatory for CNFC events) to be added to ALL events (declared mandatory for CNFC events) kieran mccarthy 07 Jun 2023 confirm is is compulsory and a value will need to be set for all event definition. in NCMP a default value of 'ncmp' can be used if no other source is applicable. Toine Siebelink will update this page were needed to add this field and default value
