bulk insert overwrite table will delete the table and then recreate a table

When hoodie.sql.bulk.insert.enable is enabled, executing insert overwrite will delete the table and then recreate a table, so time travel cannot be performed.

 
{code:java}
create table hudi_cow_test_tbl (
  id bigint,
  name string,
  ts bigint,
  dt string,
  hh string
) using hudi
tblproperties (
  type = 'cow',
  primaryKey = 'id',
  preCombineField = 'ts',
  'hoodie.sql.insert.mode' = 'non-strict',
  'hoodie.sql.bulk.insert.enable' = 'true'
);

insert into hudi_cow_test_tbl select 1, 'a1', 1001, '2021-12-09', '11';

insert overwrite hudi_cow_test_tbl select 3, 'a3', 1001, '2021-12-09', '11';
