An internal report from cross-engine write-path instrumentation: with individual writes slower than the idle window (a contended disk), every inter-write gap looked idle and fired a background full flush — 15 extra flushes during 100 contended adds, amplifying the very pressure that slowed the writes. The law now: an idle fire landing within the spacing floor of the last flush DEFERS to the floor boundary instead of flushing; the floor is min(interval, 10× the CONFIGURED idle window) — scaled to caller intent (a tiny idle window keeps fast idle-driven durability; default 2s/30s config gets a 20s floor), derived from the configured idle, never from a deferred re-arm delay (which would compound into runaway deferral). Deferred is never dropped: a lone write on a then-quiet store still persists at the floor without any further write arriving. Pins: the contended-shape pin (six slow-spaced writes fire ≤2 idle flushes, not one per gap; then still persist) + the original quiet-store idle pin unchanged. Unit 2055/2055. |
