Дашборд тормозит 5 секунд на каждой загрузке из-за тяжёлой агрегации? В Postgres это чинится одной командой — без Redis. VIEW не спасёт: это просто сохранённый текст запроса, агрегация гоняется заново каждый раз. А MATERIALIZED VIEW хранит готовый результат на диске — любой SELECT отдаёт его за ~50 мс вместо 5 секунд.

Chat2DB gom SQL client và AI assistant vào cùng một workspace, hỗ trợ hơn 30 database như MySQL, PostgreSQL, Oracle, ClickHouse, MongoDB và Redis. Điểm đáng thử: text-to-SQL, query history, chỉnh dữ liệu, biểu đồ, ER diagram và chạy local-first. Nhưng SQL do AI tạo vẫn phải review trước khi execute. Dùng AI như copilot, đừng dùng như autopilot. #repo #claude #codex #cursor #zendeveloper
