## 2.2.1

*发布日期: 2024-10-09*

### Features
- 在时序引擎中,支持数据补录。

### 增强
- 使用 `dldump` 工具进行备份与还原时,添加了进度条。
- 系统重启时,将根据 CPU Core 数量,对于 `wal` 进行并性重放,以加速系统启动。
- 使用 InfluxDB 行协议写入,所有 `tag` 做为 partition key。
- 缓存更多数据的统计信息,以加速查询。

### 修复
- 当 partition key 为多列时,修复分区信息计算可能不正确的问题。

### 其他
- 对表 column 的数量限制。


## 2.1.11
