}

Fields

keep_days: i64

Keep everything newer than this many days before the journal’s newest action (journal-relative, not wall-clock).

dry_run: bool

cap_bytes: Option<u64>

Store size ceiling (apparent bytes). When exceeded, the oldest evictable actions are removed — rows AND objects — until within the cap. Pins and the hot window are absolute floors. None = no cap.

min_free_bytes: Option<u64>

Minimum free space on the store’s filesystem. Below it, eviction runs exactly like the cap. None = no floor. NOTE: the automatic post-hook trigger deliberately passes None here — deficit-driven eviction destroys history over pressure that is usually NOT doover’s fault (and frees ~0 physical bytes on CoW filesystems), so it only ever runs from an explicit doover gc, where the report is in front of the user.

time_budget: Option<Duration>

Wall-clock ceiling for the EVICTION loop (D1 discipline). On expiry the pass stops cleanly with still_over_budget = true; a later pass resumes where the row order left off. None = unbounded (manual gc).
