The interplay between mutable_linger_seconds, late_arrive_window and persist_age_threshold_seconds can be tricky to reason about. I realized that the lifecycle rules can be simplified by removing mutable_linger_seconds and instead using late_arrive_window_seconds for the same purpose. Semantically, they basically mean the same thing. We want to give data around this amount of time to arrive before the system persists it, which gives it more of an opportunity to persist non-overlapping data.
When a partition goes cold for writes, after we've waiting past this window, we should compact and persist that partition. This removes one unnecessary knob from the lifecycle configuration and also removes the potential for conflicting configuration options.
