### 1. Minimal reproduce step (Required)
tpcc 100 warehouse data prepare, set tiflash replica , run some time. Then run the follow sql
```sql
SELECT
T.o_ol_cnt,T.order_line_count
FROM
(
SELECT
o_ol_cnt,
order_line_count
FROM
orders
LEFT JOIN (
SELECT
ol_w_id,
ol_d_id,
ol_o_id,
count(*) order_line_count
FROM
order_line
GROUP BY
ol_w_id,
ol_d_id,
ol_o_id
ORDER by
ol_w_id,
ol_d_id,
ol_o_id
) AS order_line ON orders.o_w_id = order_line.ol_w_id
AND orders.o_d_id = order_line.ol_d_id
AND orders.o_id = order_line.ol_o_id
WHERE
orders.o_w_id = 7
) AS T
WHERE
T.o_ol_cnt != T.order_line_count
```
The plan is
```
explain analyze SELECT T.o_ol_cnt,T.order_line_count FROM (SELECT o_ol_cnt, order_line_count FROM orders LEFT JOIN (SELECT ol_w_id, ol_d_id, ol_o_id, count(*) order_line_count FROM order_line GROUP BY ol_w_id, ol_d_id, ol_o_id ORDER by ol_w_id, ol_d_id, ol_o_id) AS order_line ON orders.o_w_id = order_line.ol_w_id AND orders.o_d_id = order_line.ol_d_id AND orders.o_id = order_line.ol_o_id WHERE orders.o_w_id = 7) AS T WHERE T.o_ol_cnt != T.order_line_count;
