This issue is hard to reproduce, it happens 10 times in last 24 hours

duration_hr is a field with type Decimal (13, 4), I found some abnormal conversion during the ClickHouse replication, as below:
```
MySQL     ClickHouse
0.3333 -> -2147483653.2202
0.5000 -> -2147483653.0535
0.1667 -> -2147483653.3868
0.0833 -> -2147483653.4702
0.7500 -> -2147483652.8035
```
As you can see, a weired one among the normal ones:
