PostgreSQL Python Tutorial

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. В 100 раз быстрее. Нюанс: сам не обновляется — нужен REFRESH (обычно по расписанию). Зато, в отличие от Redis, его можно индексировать, фильтровать в SELECT и джойнить как обычную

We are right in the middle of Burmese python nesting season in South Florida, and one recent discovery is highlighting just how adaptable this invasive species has become. A python was found hiding underneath a sidewalk, guarding 20 eggs in Cutler Bay.⁠ ⁠ The snake was discovered by a man walking nearby, who noticed movement under the concrete. What he saw next was something most people would never expect in a neighborhood setting.⁠ ⁠ #python #burmesepython #nestingseason #wildlife #snake
