### Создание соединения с базой данных (Engine)

В SQLModel объект соединения `engine` (по сути это `Engine` из SQLAlchemy) **содержит пул соединений** к базе данных.

Для обеспечения всех подключений приложения к одной базе данных нужен только один объект соединения `engine`.

# OpenAPI Webhooks { #openapi-webhooks }

There are cases where you want to tell your API **users** that your app could call *their* app (sending a request) with some data, normally to **notify** of some type of **event**.

This means that instead of the normal process of your users sending requests to your API, it's **your API** (or your app) that could **send requests to their system** (to their API, their app).

This is normally called a **webhook**.

            String n = f.getName();
            return n != null && !n.isEmpty() && n.endsWith(".txt");
        };

 *  Fix: Don't crash if the connection is closed when sending a degraded ping. This fixes a
    regression that was introduced in OkHttp 3.14.5.
