测试60多万的数据插入表时不识别自增主键，当增加limit限定能识别自增主键

测试环境：版本：doris-2.1.4-rc02
测试自增主键功能：test_source：637486（60多万数据量），将其插入到test_sink表
----------test_sink 表的建表语句
create table test_sink
(
id bigint not null AUTO_INCREMENT(1),
name string
)
UNIQUE KEY(id)
DISTRIBUTED BY HASH(id) BUCKETS 10;

测试SQL：
INSERT INTO test_sink(name) select name from test_source;

  查看报错信息如下：
      Reason: column_name[id], null value for not null column, type=BIGINT. src line []; 
      Reason: column_name[id], null value for not null column, type=BIGINT. src line []; 

将上述测试SQL加上 limit 限定，数据正常插入，这个情况怎样解决
INSERT INTO test_sink(name) select  name from test_source limit 637486;
mysql> select count(1) from test_sink;
