Set 42 days expiration time for Redis HLL metrics
Here we have defined known events, with some attributes https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data_counters/known_events.yml the initial implementation had set 12 weeks, expiration time(84 days)
As the counters get data for the last 4 weeks I would say it could be enough to have 42 days
