TedTed added a comment to T280385: Apache Beam go prototype code for DP evaluation.

Small update: The Apache Beam Go SDK is about to officially become stable. Privacy on Beam's 1.0.0 release can be considered stable as soon as it's done.

Thanks @Htriedman for the deep dive. A few notes on our tooling, in case this helps:

TedTed added a comment to T280385: Apache Beam go prototype code for DP evaluation.

Side-note inspired by a remark from my colleague Mirac: given that the sensitivity is fixed to 1 in the code (which makes sense if using a pageview as the privacy unit), what is the meaning of setting it to a different value in the web UI?

Ah, I see. Yeah, no anonymization notion can change the fact that some data might be available without any guarantee because of some auxiliary release.

potentially might allow the release of data from years back with ability to do re-runs

Open question: Would using a fingerprint user-identifier based on user-agent and IP as privacy-unit? I can't picture what would be the downside of such an approach.

It seems that next steps are to do some tryouts exploring the idea of "a single view" as a privacy guarantee and try the end to end tool for DP (thanks for releasing that!). It might not get to this for a month due to personal reasons but it is on my radar.

This is super helpful, thank you. I see there is a view_count field there. Do I understand correctly that it means that the data was already aggregated? Say that field has value 5, does it means that the page had 5 different views, potentially from 5 different users (but all with the same country, user_agent_map, etc.)? If so, what is the typical distribution of values for view_count?
