> Currently, data types defined in DDL will be converted to {{TypeInformation}} and use {{TypeStringUtils}} to serialize/deserialize which will lose the precision and nullablitiy information. 
> We can use {{LogicalType#asSerializableString}} and {{LogicalTypeParser}} to serialize/deserialize data types which keeps all the information. But we need to figure out how to keep compability with previous versions.
