Decision

  1. Get
  2. Create
  3. Update (Put)
  4. Patch
  5. Delete

if many what is the priority?

...

agreed with kieran mccarthy 

Only Get (read)

(in future other operations might be support batch option too)

...

Which datasources should be supported?

...

Do we need to support passthrough-only no-cached() data only ?
(maybe just start with that, support cached data bulk request later)

...

agreed with kieran mccarthy :

all passthrough datastores will be supported

Not implemented (yet) response, for non passthrough datastores 

...

We had an internal review with some of our rApp colleagues around some of the recent proposed NCMP batch interface and they came back with some valid comment.  The proposal is that we should not distinguish batch from bulk or other flavors of read/write. 

The aim is to only have a single flavor of interface for read or write for clients.  Therefore the proposal is to drop “batch” from the interface URL and just act toward “data”

...

Agreed with team kieran mccarthy 

POST http://localhost:8080/ncmp/v1/data&topic=my-topic-name

...

CPS prefers keep interface similar as single cm handle interface (consistency and cost)

Existing : ...&topic=topicParamInQuery

...

agreed with kieran mccarthy : Follow the existing interfaces as much as possible for consistency and efficiency

...

support in ONAP DMI-plugin

...

agreed with Toine Siebelink : ONAP plugin can respond with not implemented yet code,

...

Response always Async ie. topic is compulsory ?

...

Agreed with kieran mccarthy :

Topic is optional but system will respond with 'Not implemented (yet when not specified or blank

...

Agreed with kieran mccarthy : NCMP wil only forward to client topic no handling tracking or any responses or status of request

...

Agreed with kieran mccarthy :
No response for 4b then send an error response to the topic given by client

...

Agreed with kieran mccarthy :
NCMP can log error when forward to 'client topic' Security not in scope (yet)

...

Suggestions

  1. Silently ignore
  2. (initial) error response
    1. should we combine all errors in one message?

...

Agreed with kieran mccarthy :

Additional error (messages) response with all cm-handles that cannot be resolved, also a separate error message wil be sent for each failed DMI

Issue

Notes 

Decision

1Which operation(s) need support for multiple cm handles?
  1. Get
  2. Create
  3. Update (Put)
  4. Patch
  5. Delete

if many what is the priority?

agreed with kieran mccarthy 

Only Get (read)

(in future other operations might be support batch option too)

2

Which datasources should be supported?

Do we need to support passthrough-only no-cached() data only ?
(maybe just start with that, support cached data bulk request later)

agreed with kieran mccarthy :

all passthrough datastores will be supported

Not implemented (yet) response, for non passthrough datastores 

3URL  pattern for NCMP bulk endpoints

We had an internal review with some of our rApp colleagues around some of the recent proposed NCMP batch interface and they came back with some valid comment.  The proposal is that we should not distinguish batch from bulk or other flavors of read/write. 

The aim is to only have a single flavor of interface for read or write for clients.  Therefore the proposal is to drop “batch” from the interface URL and just act toward “data”

Agreed with team kieran mccarthy 

POST http://localhost:8080/ncmp/v1/data&topic=my-topic-name

4keep datastore, topic and optional parameters in the URL itself instead into body.

CPS prefers keep interface similar as single cm handle interface (consistency and cost)

Existing : ...&topic=topicParamInQuery

agreed with kieran mccarthy : Follow the existing interfaces as much as possible for consistency and efficiency

5

support in ONAP DMI-plugin


agreed with Toine Siebelink : ONAP plugin can respond with not implemented yet code,

6

Response always Async ie. topic is compulsory ?

Assume topic is compulsory (defined in OPenApi) → Response therefore wil be 400 if not supplied

Agreed with kieran mccarthy :

Topic is optional but system will respond with 'Not implemented (yet when not specified or blank

7Should NCMP Amalgamate Async responses from DMI-Plugin before forwarding ?step 6 in flow diagram

Agreed with kieran mccarthy : NCMP wil only forward to client topic no handling tracking or any responses or status of request

8Handle non responding dmi-plugin

Agreed with kieran mccarthy :
No response for 4b then send an error response to the topic given by client

9Should (can) NCMP check if 'MyTopic' specified by client existConsider Access Control too. For now NCMP can log error. Client is responsible for topic setup

Agreed with kieran mccarthy :
NCMP can log error when forward to 'client topic' Security not in scope (yet)

10How to handle non-existing CM-Handles (id)

Suggestions

  1. Silently ignore
  2. (initial) error response
    1. should we combine all errors in one message?

    1. Do we need to send only one response containing all the requested cm handles ?
    2. Send single response for each cm handle? This could lead to to much data in the event for large batch requests. Csaba Kocsis , Sourabh Sourabh and Toine Siebelink proposed to us single event for each cm handle
    3. Single response message per DMI plugin? Just is a list of IDS should be OK.

kieran mccarthy  Confirmed in meeting  

15Message format for the batch interfaceWe have had some internal discussions including with some O-RAN standards representatives and one of the outcomes is that it would be good if we aligned with the some community standards for event header definitions.  IT is proposed (initially from AT&T) that we should follow Cloud Native Computing Foundation (CNCF) specification as defined in their cloudevents incubator project.
Some non-standard headers wil need to be implemented as 'extensions' and names to be confirmed

kieran mccarthy and Team agreed on and some cost (1-2 days) is acceptable 

18What would be the field name of response data?data.responses[0].data

kieran mccarthy please confirm : we are using 'responseContent' as name of this field as 'data' is already used for cloud event standard payload.

Now it is like : data.responses[0].responseContent

Sourabh Sourabh Suggest to use "result".  This is after all where the actual result output.  the other tags in responses[x] are status related to the request  :

                        data.responses[0].result

Exact format of timestamp of cloud events.


CloudEvent documentation (https://github.com/cloudevents/spec/blob/v1.0.2/cloudevents/spec.md#time) refers on ISO8601 standard

(see org.onap.cps.ncmp.api.impl.utils.EventDateTimeFormatter )
