1717631 - Add telemetry for structured cloning (aka structured serialize/deserialize)

Status: RESOLVED FIXED

(Core :: JavaScript Engine, task, P3)

Description

[Steve Fink [:sfink] [:s:]]

There are a lot of places structured cloning can be used, but it's not clear which of them are perf-sensitive. We should track clones to evaluate whether it needs optimization.

PRELIMINARY NOTES:

• The data collection categories, as well as the data collection review process itself, are documented here: https://wiki.mozilla.org/Data_Collection We have conveniently included a link to this page in request.md.
• I have presumed a data collection category of 1 "Technical Data" for this collection. Please let me know if I've gotten it correct.

DATA COLLECTION REVIEW RESPONSE:

Is there or will there be documentation that describes the schema for the ultimate data set available publicly, complete and accurate?

Yes.

Is there a control mechanism that allows the user to turn the data collection on and off?

Yes. This collection is Telemetry so can be controlled through Firefox's Preferences.

If the request is for permanent data collection, is there someone who will monitor the data over time?

Yes, :sfink is responsible.

Using the category system of data types on the Mozilla wiki, what collection type of data do the requested measurements fall under?

Category 1, Technical.

Is the data collection request for default-on or default-off?

Default on for all channels.

Does the instrumentation include the addition of any new identifiers?

No.

Is the data collection covered by the existing Firefox privacy notice?

Yes.

Does the data collection use a third-party collection tool?

No.
