软删除的主要目的是避免使用 delete 语句，导致一些数据丢失的重大问题，合理的数据库备份归档习惯可以避免这个问题。

我们比较常用的方法是用另一个归档表，避免 status <> 'delete' 或 deleted 判断，不然很简单的查询操作都需要判断是否删除，比如 `select count(id) from message_table` ,更不用提复杂查询了。

归档表 + 测试用例覆盖可以解决大部分删除场景

前些天一直在找便宜的云服务器，偶然间发现一免费的云平台，这里推荐给大家。

就是阿贝云，网站是https://www.abeiyun.com

说一下感受

1、阿贝云虽然是一小众的云平台，重在免费，该有的东西都有，还能免备案这是最舒服的。

2、使用了一天，上了项目，网速不慢。

3、唯一要指出来就是磁盘太小。

拉取了rustbuster的v3.0.3版本文件, 二进制文件无法使用, 执行结果如下:

```bash

  Failed to find OpenSSL development headers.

  You can try fixing this setting the `OPENSSL_DIR` environment variable
  pointing to your OpenSSL installation or installing OpenSSL headers package
  specific to your distribution:

      # On Ubuntu
      sudo apt-get install libssl-dev
      # On Arch Linux
      sudo pacman -S openssl
      # On Fedora
      sudo dnf install openssl-devel

  See rust-openssl README for more information:

      https://github.com/sfackler/rust-openssl#linux

  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
warning: build failed, waiting for other jobs to finish...
```

经过检查openssl与rust均为最新版本, 

```bash
[root_cn@archlinux target]$ sudo pacman -S rust
[sudo] password for root_cn:

在网上找了一下, 查到资料, 在[rust-openssl的issues](https://github.com/sfackler/rust-openssl/issues/1227)中提到类似报错, 得到解释如下:

> If you are cross compiling to MUSL, you either need to point openssl-sys to the location that you have a copy of OpenSSL cross compiled to MUSL, or tell it to build a copy of OpenSSL itself with the vendored feature.
>
>	如果你是交叉编译到MUSL，你需要将openssl-sys指向你有一个交叉编译到MUSL的OpenSSL副本的位置，或者告诉它用vendored特性构建一个OpenSSL本身的副本。

由于不会rust, 依靠关键词"交叉编译"+"cargo"搜索到了[cargo交叉编译rust程序](https://blog.csdn.net/tyc880616/article/details/104371502), 顺着找到文件:

```
[root_cn@archlinux .cargo]$ cat ~/.cargo/config
[source.crates-io]
replace-with = 'sjtu' # 指定使用下面哪个源，修改为source.后面的内容即可

# 中国科学技术大学
[source.ustc]
registry = "https://mirrors.ustc.edu.cn/crates.io-index"

# 上海交通大学
[source.sjtu]
registry = "https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index/"

# 清华大学
[source.tuna]
registry = "https://mirrors.tuna.tsinghua.edu.cn/git/crates.io-index.git"

# rustcc社区
[source.rustcc]
registry = "https://code.aliyun.com/rustcc/crates.io-index.git"
```

没有找到交叉编译的设置, 由于本人不会rust, 线索断了, 尝试向大家寻求一波帮助, 非常感谢阅读.

一些数据可能会被用户主动删除，或者管理员删除（内容安全、审核等），之前的做法都是用 status 字段，或者增加一个 deleted 标志字段（boolean），但这样做的话一些 SQL 语句不太好写，各位都是怎么做的？最佳实践？
