1612280 - Improve documentation of application lifetime

Status: RESOLVED FIXED

(Data Platform and Tools :: Glean: SDK, defect, P1)

Description

[Michael Droettboom [:mdroettboom]]

The unexpected issues with application lifetime that were discovered while investigating the issues with gfx.compositor should be documented.

Effectively, something like: "Application metrics should always be set at startup during every run of the application. If there is a possibility that it won't be set during some runs, but it always required in every ping, user lifetime is probably a better choice."

Thinking of this a bit, we might want to rephrase it slightly: this caveat for lifetime: application is only true for the metrics ping. Custom pings might work differently. I'd also drop the recommendation of using user lifetime: I think we should rather encourage custom pings, rather than stick permanent data to user profiles.
