RunTime DB:
1 High Level Component Definition and Architectural Relationships
The RunTime DB function provides storage for real-time run-time parameters that need to be used by ONAP. It provides
PURPOSE:
REPOSITORY - The types of data that is stored in the Run-Time data storage repository for: (1) configuration parameters used by xNFs in run time and (2) operational parameters used by ONAP and xNFs.
- DATA LAKE - It is designed to be a common services data layer which can serve as a data lake.
- SYNCING - The RunTime DB enables the ability to sync data between ONAP & the xNFs. (The source of truth can be define).
- CM FUNCTIONS - Enables OSS configuration, optimization, and LCM operations. (FUTURE)
- CM FUNCTIONS - Enables future CM & Data management functions such as xNF Crash restoration, data restoration, data history management and auditing. (FUTURE)
- CENTRAL/DISTRIBUTED - Because it is a common service, it is part of an ONAP installation, so it could be deployed with either an Edge ONAP installation or a centralized ONAP installation. (FUTURE)
- SCOPE - The Run Time DB could also serve as the data storage to store for example ONAP Policy Rules, CLAMP Control Loop, Operational Views (FUTURE)
ACCESS (READ/WRITE):
- READ ONLY - Run-Time parameters can be READ by any ONAP platform component and any ONAP plug-in. Examples of ONAP platform components are A&AI, SDC, SDNC etc.
READ/WRITE - Parameters can be READ/WRITE from Controllers, DCAE (future), VES Collector/DMaaP, A&AI, Policy/CLAMP (future) and other components with permission settings.
- DEFAULT - SO (future), DCAE, A&AI, Controllers (CDS, APPC, SDNC) will have default read/write access to RunTime DB
- DEFINABLE - Other components will have default read-only access to RunTime DB but can be given Read/Write access on a per record basis.
SYNCING (INVENTORY):
ELEMENT SYNC - Software keeps the A&AI elements with the elements in the RunTime DB in Sync.
- A&AI - A&AI is still the master of valid entities in the network and provides a dynamic view of the assets (xNFs) available to ONAP
- RUNTIME DB - The RunTime DB is a master of the associate (exo-inventory) data associated with the entities.
- DYNAMIC VIEW - When a xNF appears or is removed from the system, RunTime DB records will be added/removed based on A&AI entries.
INDEXING:
- INDEXING - Data Records will be indexed by xNF (VNF, PNF, ANF).
- RETRIEVAL - How are data records retrieved efficiently. This relates how the records are indexed.
2. API definitions
RunTime DB provides the following interfaces:
| Interface Name | Interface Definition | Interface Capabilities | Version | Status | Consumed Models |
|---|---|---|---|---|---|
| RTDBE-1 | RunTime DB Interface. | An interface to create, update, retrieve, query, delete information from the RunTime DB. ACCESS: - SO, DCAE, A&AI, Controllers (CDS, APPC, SDNC) will have default read/write access to RunTime DB - Other components will have default read-only access to RunTime DB but can be given access on a per record basis. | |||
| RTDBE-2 | RunTime DB Graphical User Interfaces | Provides the capability to view and edit the data currently in the RunTime DB. |
Note: xxxI interface is a Component internal interface. xxxxE interface is a component external interface
The current API documents can be found at:
RTDB consumes the following Interfaces:
| Interface Name | Purpose Reason For Use |
|---|---|
| SDCE-7 | To receive the service and resource artifacts from SDC. STEPS: (1) ONBOARDING - A vendor onboards artifacts describing the parameters supported for their PNFs and VNFs. (2) SDC CATALOG - The onboarded artifacts are stored in the SDC Catalog after onboarding and validated (VNF-SDK). (3) CSAR DISTRIBUTION - The contents of the artifacts are distributed by SDC in a CSAR package onto the DMaaP bus. (4) SETTING UP RUNTIME DB - S/W to setup the RunTime using the content of the CSAR package consumes the SDC CSAR Package. |
