通过 ProxySQL 代理访问，执行无 JOIN、无聚合、无排序、无 LIMIT 的简单单表过滤 SQL，
偶发静默返回固定 800001 行数据，正常数据量为 100 万 + 行，无任何报错。
审计日志如下图确实返回800001行数据
sql“
select open_id as open_id
from hive_ads.ads_market_reg_cust_label_df
where open_id is not null
and open_id <> ''
and last_credit_apply_status not like '%ACE%'
and last_credit_apply_status not like '%APS%'
and open_id is not null
and open_id <> ''
第二个demo，返回应该是4条记录，但是实际只返回1条
SELECT '1' as aa
union all
SELECT '2' as aa
union all
SELECT '3' as aa
union all
SELECT '4' as aa
