If the data is out of order, when receive data with the new schema and then
trigger the Schema Change; Next , the data with old schema arrive , may also
trigger the Schema Change , so it is also problematic to change the schema
through the data.
```
data send order is :
{"id":"1","name":"2","tm":1}
{"id":"2","name":"2","tm":2}
{"id":"3","name":"3","age":3,"tm":3}
but data receive order is :
{"id":"1","name":"2","tm":1}
{"id":"3","name":"3","age":3,"tm":3}
{"id":"2","name":"2","tm":2}
id with 2,3 is out of order , this may cause trigger the Schema Change many
time
```
