Integration pattern for current, historical, temporal, timeseries, etc.

The CPS project proposal covers multiple types of storage.

How will it integrate several DBMS technologies to support these different needs?

YesOption C. Loose coupling. The focus of the PoC will be on current storage and model driven notifications to drive data towards other data stores.

Backward Compatibility with Config DBThe current API is a basic hard coded REST interface with specific methods supporting 2 object types and a few operations. Although extensible it will be hard to keep the new proposed interface backward compatible with the original API.YesNo Compatibility. Either a adapter will be provided later of some resource will be set reserved to migrate the existing client to the new service when available.

Interface style

The access interface needs to suit the users of the data. It must also acknowledge the underlying data structure.

There are two main options: Providing behavior interfaces on a logical representation of the data; Providing behavior interfaces on the CPS and explicitly providing reference to the data

YesOption B, Access methods on the CPS; Data object provides context to those methods.

Data RepresentationThe data that is read from and written to the CPS must comply with a known format. This is relevant to both Java and REST interfaces. The choices here are to provide generic objects/documents, or highly typed (using model info).YesOption A. Data will be represented as documents (REST) and or generic objects (glorified maps in Java)

Flow of models into the systemThe CPS will be model driven, which means that new models can be added to the CPS. How will models be introduced to the CPS from other components in the ONAP system or the network?No

Upgrade of models

As the network functions evolve, new versions of models will be introduced that will replace existing models for new versions of the NF. These new versions will need to co-exist alongside existing versions, such that different NF versions can be modelled using the appropriate model version

Specifiy and configure CPS behaviorThe behavior of the CPS needs to be driven by a model. The native model language of CPS is YANG. There are several mechanisms available to achieve this need. One needs to be selectedNo

Location of PoC CodeDan Timony suggested to use and existing CCSDK repo, he mentioned ccsdk/features. As long as the PoC remains completely independent and doesn't affect delivery of existing artifacts in the same repo.Yesccsdk/features, see  https://gerrit.onap.org/r/c/ccsdk/features/+/110385 (awaiting approval)

Common information model, Data lake and Access controlHow will the CPS help with managing coupling between ONAP components that make use of data lake and common information modelYes

We will start with Architectural Approach A in the PoC with the aim of fully supporting Architectural Approach C.

I.e. access to the data lake will be conditional on permission granted by the data owner. In the PoC we will not implement the permission granting mechanism
