How to support digit column name

[muyihao]

Due to business requirements, we must use field names that start with a number. However, this violates Avro's naming conventions. Therefore, I am wondering if there is a way to work around this limitation. From an implementation perspective, would it be feasible to modify Avro's code to support field names that start with a number? If there are better solutions, please let me know.

You could use a custom RecordFieldNameValidator
