1873935 - [service-telemetry] Consider dropping the collected but not sent data from Focus/Klar ios

Status: RESOLVED WONTFIX

(Data Platform and Tools :: Glean: SDK, task, P4)

Description

[Alessio Placitelli [:Dexter]]

As outlined in this comment we're removing service-telemetry from Focus/Klar Android, but there might be a chance for some of the data to be left on the disk without having the opportunity to be sent. We should likely be deleting that data. However, given that:

I don't think it's worth the engineering work to create something "purge" it. Given the average size of the Glean storage database in Fenix (< 200kb), assuming the same conditions apply to Focus, I don't think it should be too much of a big deal?

And that Klar Android has telemetry off by default, plus that this space will eventually be reclaimed if reinstalling, I don't think it's a pressing issue. Filing this for tracking the rationale in a bug.
