MySQL9.0最新版单库表数量超过10000时会触发crashing的Bug
数据量超过10000+的时候重启服务会触发,报错如下:

Most likely, you have hit a bug, but this error can also be caused by malfunctioning hardware.
Thread pointer: 0x0
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains
information that should help you find out what is causing the crash.
浮现过程:
创建数据库,新建10000张以上的表,重启服务,就会crashing
下面使用python脚本创建:
import pymysql
conn = pymysql.connect(
host='localhost',
port=3306,
user='root',
password='youpassword',
)
for i in range(10001):
cursor = conn.cursor()
cursor.execute(f'create table test.t20240712_{i}(id int, name varchar(200))')
data = cursor.fetchall()
conn.commit()
修改里面的脚本,直接运行即可。
影响版本:
MySQL 8.0.38
MySQL 8.4.1
MySQL 8.4.0
MySQL 9.0.0
不受影响版本:
MySQL 8.0.37
MySQL 5.7.44
其他版本暂未做测试。

单库表的数量达到1万个表以上,基本上不可能达到这个量级吧
