Event Processors
- DCAEGEN2-2258 - Data Exposure Service (DES) under DataLakeDataLake POCHandlers framework.
Analytics/RCA
- DCAEGEN2-2255 - Slice Analysis mS
Following service is retired for Honolulu
- TCA (cdap) - Replaced by TCA-gen2 (introduced in Frankfurt release)
For Honolulu, new MOD Front-End and Back-end components is being worked as PoCtracked under REQ-326 -Self Serve Control Loops will continue - DCAEGEN2-2313 (this would eventually replace NiFI based UI/processor in subsequent ONAP release)
3. New or modified interfaces
Architecture diagram - DCAE R8 M2 Release Planning#Highlevelarchitecturediagram
New External interfaces
- Data Extraction Service API - Provides basic computation and data retrieval/access from datastorage maintained by DL handlers (Feeder). This API will be consumed by Slice Analysis MS (DCAE) and UUINone for H release
Modified interfaces
- VES Collector (7.2 VES support)
...
Relies on k8s for loadbalancing and scaling. DCAE platform handles the control flow and do not carry the data/event; DCAE service components can be scaled and support state management through external DB and/or K8S state management.
Cloudify is 3rd party product; multi-site feature on community version will be available later in 2020; will be incorporated for G release.
As DCAE collectors are extensively used in all ONAP usecase, performace testing has been done on below collectors
