### 创建引擎（Engine）

SQLModel 的引擎 `engine`（实际上它是一个 SQLAlchemy `engine` ）是用来与数据库**保持连接**的。

您只需构建**一个 `engine`**，来让您的所有代码连接到同一个数据库。

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[14:18] hl[14:15,17:18] *}

使用 `check_same_thread=False` 可以让 FastAPI 在不同线程中使用同一个 SQLite 数据库。这很有必要，因为**单个请求**可能会使用**多个线程**（例如在依赖项中）。

不用担心，我们会按照代码结构确保**每个请求使用一个单独的 SQLModel *会话***，这实际上就是 `check_same_thread` 想要实现的。

Some upgrade methods might upgrade etcd from 3.0 to 3.1 automatically when you upgrade from Kubernetes 1.8, unless you specify otherwise. Because [etcd does not support downgrading](https://coreos.com/etcd/docs/latest/upgrades/upgrade_3_1.html), you'll need to either remain on etcd 3.1 or restore from a backup if you want to downgrade back to Kubernetes 1.8.
