From 3557ae283fc64d368799f9f264ef24b3bb2e1ce6 Mon Sep 17 00:00:00 2001 From: Ping Qiu Date: Mon, 9 Mar 2026 17:44:01 -0700 Subject: [PATCH] feat: Phase 10 CP10-3 -- NVMe/TCP Tier 1 optimizations, WAL admission control, benchmark platform CP10-3 Tier 1 optimizations (T1-T4): - TCP_NODELAY + 256KB socket buffers on NVMe/TCP connections - Response batching: all C2H data chunks + CapsuleResp in single flush - Tiered buffer pool (4KB/64KB/256KB sync.Pool) for write payloads - Configurable MaxH2CDataLength wiring through controller/IC/chunking BUG-CP103-1: NVMe write retry with jittered backoff for transient WAL pressure - writeWithRetry() with bounded backoff [50/200/800ms] - throttleOnWALPressure() pre-write delay above 90% WAL usage - WALPressureProvider interface + NVMeAdapter.WALPressure() BUG-CP103-2: Volume-level WAL admission control - WALAdmission with counting semaphore (max concurrent writers) - Soft watermark (0.7): small delay to desynchronize herd - Hard watermark (0.9): block until flusher drains - Single-deadline budget shared across watermark wait + semaphore - Close-aware during both watermark and semaphore waits - Wired into BlockVol.WriteLBA() and Trim() Benchmark platform enhancements: - NVMe benchmark actions and scenarios (A/B, CW sweep, IOQ sweep) - Database benchmark actions (SQLite, pgbench) - K8s operator QA reconciler tests - New testrunner scenarios for HA, fault injection, CSI lifecycle Test counts: 213 NVMe + 625 engine + operator + testrunner tests, all passing.
