傳統 Serverless 運算因無狀態與高並發特性，極易導致資料庫連線數（Connection Pool）瞬間耗盡。Vercel 發表全新解決方案，透過在基礎設施層面進行智慧連線管理與代理，免去開發者手動設定 PgBouncer 等複雜工具的痛苦。此舉不僅大幅降低冷啟動延遲，更能確保在高流量下資料庫依然穩定運作。
One of the greatest challenges developers face in serverless architectures (such as Vercel Functions) is managing connections to traditional relational databases (like PostgreSQL and MySQL). Because serverless functions scale dynamically and have short lifespans, each invocation may establish a new TCP connection. Under high-concurrency traffic, thousands of function instances can simultaneously attempt to connect to the database, quickly exhausting the database's maximum connection limit (Max Connections Limit) and causing the application to crash or return connection errors.
