The CDS Non-Functional Requirements (NFRs) cover considerations including:
"Maximum traffic expectations for data holders. Included to ensure there is a ceiling for the amount of traffic that a data holder is expected to service."
Do these thresholds apply at the Data Holder level, to the aggregate traffic for all brands of a Data Holder. Alternatively, do these thresholds apply to the traffic for each brand of a Data Holder?
The maximum traffic expectation applies to each master brand belonging to a Data Holder.
In the CDS CDR Federation section, a Data Holder is clarified as being represented by a single entry in the Register:
For the purposes of this standard a single designated organisation may be represented via the Register as multiple separate Data Holders to support multiple brands or market identities.
This means that each master brand with a separate registration must support the NFRs.
