PostgreSQL Antipatterns: когда мешает внешний ключ

Внешние ключи (foreign keys) - мощный и удобный механизм контроля логической целостности данных в базе. Но он бывает не только лишь полезен, и может неплохо пригрузить вашу БД.

Внимательный взгляд на план запроса поможет избежать многих проблем - как при чтении из базы, так и при вставке в нее.

Две задачи при работе с объектным хранилищем: как правильно создать кастомную ссылку одноразовой загрузки и не ошибиться

Каждый день сотрудники техподдержки Selectel решают задачи клиентов. Что-то не подключается, что-то вдруг удалилось или потерялось. Для ответа на часть тикетов достаточно скинуть инструкцию из базы знаний, но некоторые становятся настоящими техническими квестами.

Сегодня мы решили разобрать несколько из них. В этой подборке все они связаны с работой облачного объектного хранилища. Сейчас в Selectel миграционные каникулы — можно 30 дней не платить за запросы и хранение данных.

Ответы на одну из задач убрали в «спойлеры» — проверьте себя, сможете ли вы сами найти решение на основе «дано». Если вам понравится такой формат текстов, пишите в комментах или голосуйте в опросе, — сделаем еще. А пока — смотрите под кат.
