> Assume that there are only two fields name and age in table hudi_table.
> 1、Schema evolution is supported when DDL operations are executed
> concurrently. For example, if "alter table hudi_table add columns(gender
> string after name); " and "alter table hudi_table9 add columns(score int);"
> are executed concurrently, the submitted schema must contain the gender and
> score columns.
> 2、Schema evolution is supported when DDL and DML operations are executed
> concurrently. For example, if "alter table hudi_table add columns(gender
> string after name);" and "insert into hudi_table values("Richard", 18);" are
> executed concurrently, the submitted schema must contain the gender column
> and the data inserted into hudi_table can also be written.
