MySQL

Движок MySQL позволяет выполнять SELECT запросы над данными, хранящимися на удалённом MySQL сервере.

Формат вызова:

MySQL('host:port', 'database', 'table', 'user', 'password');

На данный момент простые условия WHERE, такие как =, !=, >, >=, <, <= будут выполняться на стороне сервера MySQL.

Остальные условия и ограничение выборки LIMIT будут выполнены в ClickHouse только после выполнения запроса к MySQL.
