> @Zouxxyy hello, wanna ask a question, if we load create table with defalt
value's logical plan, the default filed should put in where? In fields?
Since Paimon already has a prop for default values, we can just use that,
what do you think @JingsongLi
So I think we can implement it in the following steps:
1. Support Paimon's built-in default value syntax for spark reading (this is
actually your first PR)
```sql
CREATE TABLE T (id INT, name STRING)TBLPROPERTIES
('fields.name.default-value' = 'x');
```
2. Support Spark's DDL syntax (for Spark version 3.4 and above), which will
save 'fields.name.default-value' to Paimon's properties.
```sql
CREATE TABLE T (id INT, name STRING DEFAULT 'x');
```
