Hi everyone,
We are planning to implement a change to aggregation coordinator selection in M119 (currently in Beta)
As part of this change, we will be deprecating the “PrivacySandboxAggregationService” parameter. If you are currently doing local testing, then you will need to make the following change to avoid any incompatibility:
Begin using the new parameter “AggregationServiceMultipleCloudProviders:aws_cloud” (default option) or “AggregationServiceMultipleCloudProviders:gcp_cloud” to specify the origin for the GCP public key endpoint.
Example: --enable_features="AggregationServiceMultipleCloudProviders:aws_cloud/https%3A%2F%2Fmyaws.com/gcp_cloud/https%3A%2F%2Fmygcp.com”
Serve the public key at: origin + .well-known/aggregation-service/v1/public-keys path
Example: https://myaws.com/.well-known/aggregation-service/v1/public-keys and https://mygcp.com/.well-known/aggregation-service/v1/public-keys in the above example
This change will not have any impact on production testing
Please reach out if you have any questions.
Thanks,
Akash
