flush() is durability work: it must cost what the current window's deltas cost, never what the history backlog costs. Under adaptive retention the byte budget derives from free memory, so bulk-load pressure shrank the budget exactly at peak write volume and flush paid actual reclaim inline — a production deployment measured single writes blocked 25-191s behind reclaim-on-flush. - flush() no longer calls autoCompactHistory(); close() is THE auto-compaction site (already ran there; now alone). - Every auto pass is time-bounded (CLOSE_COMPACTION_BUDGET_MS = 5s): reclamation is oldest-first, so an early stop is a consistent prefix and the next pass resumes. Explicit compactHistory() gains an optional timeBudgetMs for caller-chosen maintenance windows. - Documented trade stated where operators read: a long-lived writer that never closes accumulates history until its next explicit compactHistory() — predictable writes, explicit maintenance. Pins: flush-never-reclaims + close-reclaims-durably (db-mvcc), bounded pass stops-then-resumes as a consistent prefix (generationStore unit). |
