Ability to query key aggregate #1

Closed alois-bissuel closed 2 years ago

alois-bissuel commented 2 years ago

Hello,

One interesting evolution of the aggregation service would be to enable querying aggregate of keys. I think this was mentioned in the aggregate attribution API at a time when the aggregation was supposed to be performed by MPC rather than TEEs. In other words, I would love to be able to query a bit mask (eg for a 8 bit key, 01100*01 would be 01100101 and 01100001). This would enable a greater flexibility for decoding (ie chosing which encoded variables to get depending on the number of reports), and negate the need to adapt the encoding depending on the expected traffic to the destination website. Thanks! P.S. I can cross-post on https://github.com/WICG/attribution-reporting-api if needed.

Hi Alois,

thank you for the question. I think it's worth discussing. Would you mind cross-posting at https://github.com/WICG/attribution-reporting-api though? I think it's better to have API design discussions there.
