The GC procedure consists of two tiers: lookahead and purge. The lookahead tier runs less frequently (default 12 hours) than the purge tier (default 5 minutes). A lookahead round traverses the entire store and picks entries that need to be visited in the current lookahead window, pinning those entries in a separate region in the KV store, indexed by the next visit timestamp. A purge round iterates over the lookahead window only, and refreshes the entries that require a visit. It removes them from the lookahead region unless the entry requires another visit within the current window. |
