Cut /api/tasks/ p99 from ~2500ms toward ~150-300ms
Stack of optimizations against the same Hetzner→Neon transatlantic link. The trace revealed every visible ms was network/proxy overhead — DB execution itself is sub-millisecond per query (verified via EXPLAIN ANALYZE: index scans on every hot path). Connection layer: - DB_HOST → Neon pooler endpoint (-pooler suffix). PgBouncer transaction-mode keeps backend Postgres connections warm so we no longer pay the ~110ms Postgres-startup RTT on cold queries. - GORM pool tuned: MaxIdleConns 10→20, MaxLifetime 600s→1800s, MaxIdleTime added (default 0 = never close idle). - Eager pool warm-up at boot via parallel pings — first user request no longer pays the ~440ms TCP+TLS+startup handshake. - Redis maxmemory-policy noeviction → allkeys-lru. Cache writes will evict cold keys instead of erroring at the 256MB limit. Auth layer: - TokenCacheTTL 5min → 1 hour (Redis token cache). - UserCacheTTL 30s → 5min (in-memory User cache, per pod). - UserCache gains a 5,000-entry LRU cap so a flood of unique users can't blow up pod RSS. ~5MB worst-case per pod. - Token + user lookup collapsed from 2 GORM Preload queries into a single INNER JOIN. Saves 1 RTT per cold-cache request. - Auth middleware's m.db.* now use db.WithContext(ctx) so the SQL spans nest under the parent HTTP request in Jaeger. Service layer: - TaskService.ListTasks: replaced two-step FindResidenceIDsByUser → GetKanbanDataForMultipleResidences with a single GetKanbanDataForUser that uses a Postgres subquery for residence-access. One round-trip instead of two. - New CacheService residence-IDs cache: \"residence_ids_user:<id>\" with 5-min TTL. Wired into Task/Residence/Contractor/Document services for the four hot read paths that need this list. - Cache invalidation on every relevant mutation: CreateResidence, DeleteResidence, JoinWithCode, RemoveUser. DeleteResidence invalidates every member of the residence, not just the owner. What this stacks up to (Hetzner→Neon, before US migration): Path Before After (target) Cache-warm authed read ~800ms ~100-200ms Cache-cold authed read (1st in 1hr) ~2500ms ~500-700ms First request after deploy ~2500ms ~700-900ms The endgame US-region migration on top of this gets us to ~30-50ms warm-cache, but we're shippable at ~150ms warm right now.
