Description

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/iotdb/issues) and found nothing similar.

### Version

iotdb:1.2.1
windows server 2016
openjdk 11

### Describe the bug and provide the minimal reproduce step

写入iotdb为mqtt方式,之前有物理量名字不合法,中间有个空格。现在已经修改正确。
控制台情况
![Uploading 控制台报错.png…]()

### What did you expect to see?

报错日志如下
[Uploading log_datanode_compaction.log…]()

### What did you see instead?

猜测原因应该是mqtt消息可能有缓存,失败了会继续重新执行,但是不合法的消息会永久失败,可以对缓存做一定处理,如几次缓存都插入执行失败后舍弃mqtt消息内容,或者对持续插入失败的消息,单独给一个修订方式等

### Anything else?

_No response_

### Are you willing to submit a PR?

Research direction

Start by reproducing the MQTT write failure described for IoTDB 1.2.1 and inspect the reported log_datanode_compaction.log and console error. The retry and discard behavior is only proposed, so first establish the intended handling for permanently invalid cached messages; done criteria are not defined in the issue.
