| Воркеры, забившие все потоки, создавались колбэками, вызванными при приеме товарных остатков от ERP. Менеджеры выгружают остатки - работа встает. | ||
| В воркере вызывался запрос на изменение параметра у товаров, обернутый в транзакцию, в которой отключались/включались триггеры нескольких таблиц. | ||
|
|
||
| Для быстрого снятия остроты ситуации убил задачи в Sidekiq, освободив тем самым очередь. |

| 3. Пару недель назад поставил `gem pghero`, некоторое время подождал сбора статистики. | ||
|
|
||
| - Удалил 22 duplicate indexes, добавил 1 suggested index. |
| - Замерил время рендеринга каталога товаров (по логам рельс :facepalm). | ||
| - Сделал миграцию с удалением триггеров и mat.view, созданием view. | ||
| - Замерил время рендеринга каталога товаров после миграции. | ||
| - Время не изменилось, зато недопустимые затраты на поддержание mat.view перестали быть. |
