之后，对于你的生产应用程序，你可能会想要使用像 **PostgreSQL** 这样的数据库服务器。

/// tip | 提示

有一个使用 **FastAPI** 和 **PostgreSQL** 的官方项目生成器，其中包括了前端和更多工具： [https://github.com/fastapi/full-stack-fastapi-template](https://github.com/fastapi/full-stack-fastapi-template)

这是一个非常简单和简短的教程。如果你想了解一般的数据库、SQL 或更高级的功能，请查看 [SQLModel 文档](https://sqlmodel.tiangolo.com/)。

APIs. This interaction pattern causes significant loss of performance because of the write amplification. _Netflix_, for example, developed two new staging committers - the Directory staging committer and the Partitioned staging committer - to take full advantage of native object storage operations. These committers do not require rename operation. The two staging committers were evaluated, along with another new addition called the Magic committer for benchmarking.
