Как проверить размер базы данных и таблиц MySQL

Здесь рассматривается, как проверить размер баз данных, таблиц и индексов в MySQL с помощью SQL-команд, что полезно для эффективного управления ресурсами сервера и планирования расширений или оптимизаций.

Проверка использования дискового пространства MySQL
Для общего понимания, сколько места занимает директория MySQL, используйте команду Linux:

du -sh /var/lib/mysql

Эта команда показывает, сколько дискового пространства занимает директория данных MySQL, обычно расположенная в '/var/lib/mysql'.

Также, уже с помощью SQL-запросов, можно проверить следующие данные:

✔️Размер конкретной базы данных
✔️Размер всех баз данных
✔️Размер конкретной таблицы
✔️Размеры всех таблиц из всех баз данных
✔️Размер индексов

Эти команды полезны для мониторинга роста базы данных, планирования резервного копирования и оптимизации производительности.
