### --db_type
Syncer目前能够使用两种数据库来保存自身的元数据，分别为`sqlite3`（对应本地存储）和`mysql`（本地或远端存储）
Syncer目前能够使用两种数据库来保存自身的元数据，分别为`sqlite3`（对应本地存储）和`mysql` 或者`postgresql`（本地或远端存储）
```bash
bash bin/start_syncer.sh --db_type mysql
```
默认值为sqlite3
在使用mysql存储元数据时，Syncer会使用`CREATE IF NOT EXISTS`来创建一个名为`ccr`的库，ccr相关的元数据表都会保存在其中
