You don’t need Kafka: Building a message queue with only two UNIX signals It’s 2026, Just Use Postgres What canceled my Go context? Notes on Writing Wasm Go 1.26 interactive tour It’s 2026, Just Use Postgres The “Use the Right Tool” Trap You’ve heard the advice: “Use the right tool for the right job.” Sounds wise. So you end up with: Elasticsearch for search Pinecone for vectors Redis for caching MongoDB for documents Kafka for queues InfluxDB for time-series PostgreSQL for… the stuff that’s left Here’s what most people don’t realize: Postgres extensions use the same or better algorithms as specialized databases (in many cases).

Go Tool Trace

淺談 Go Tool Trace - 1 淺談 Go Tool Trace - 2 Go Trace 與使用者自訂追蹤分析 淺談 Go Tool Trace - 3 實際分析 Goroutine Analysis Go Tool Trace - 4 從 分析到實戰：最佳化 Goroutine 數量 trace trace 是「事件時間軸」，不是「取樣統計」 go tool trace：用來看 runtime trace（執行追蹤），本質是「時間序列事件」： goroutine 的建立 / runnable / running / waiting / syscall scheduler（G/M/P）相關事件、排程延遲 blocking（net / sync / syscall）時間分佈 GC 事件、STW、heap 變化（在 trace viewer 會看到） 用 pprof 是找「熱點」：誰吃 CPU / 誰 alloc 多 用 trace 是找「延遲原因」：為什麼卡（排程？鎖？網路？syscall？GC？） 直覺判斷：

I Replaced Redis with PostgreSQL (And It's Faster)

I Replaced Redis with PostgreSQL (And It’s Faster) 在更改之前，Redis 主要處理三件事： 快取（佔使用量的 70%） 發布/訂閱（佔使用量的 20%） 後台作業佇列（使用率 10%） 痛點: 需要備份兩個資料庫 Redis 使用記憶體（規模化時成本很高） Redis 持久化機制…很複雜。 Postgres 和 Redis 之間的網路跳躍 PostgreSQL 功能 1: 使用未記錄表進行快取 Redis await redis.set("session:abc123", JSON.stringify(sessionData), "EX", 3600); PostgreSQL CREATE UNLOGGED TABLE cache ( key TEXT PRIMARY KEY, value JSONB NOT NULL, expires_at TIMESTAMPTZ NOT NULL ); CREATE INDEX idx_cache_expires ON cache(expires_at); Insert INSERT INTO cache (key, value, expires_at) VALUES ($1, $2, NOW() + INTERVAL '1 hour') ON CONFLICT (key) DO UPDATE SET value = EXCLUDED.value, expires_at = EXCLUDED.expires_at; Read SELECT value FROM cache WHERE key = $1 AND expires_at > NOW(); Cleanup (run periodically)
