Hang HOU updated FLINK-29558:
-----------------------------
Description:
Hi, I use flink sql to make kafka records to mysql.
so I create these 2 tables in flink sql,here is the mysql ,and I created the
table in mysql before I did the insert action in flink sql.
CREATE TABLE mysql_MyUserTable (
id STRING,
name STRING,
age STRING,
status STRING,
PRIMARY KEY (id) NOT ENFORCED
) WITH (
'connector' = 'jdbc',
'url' = 'jdbc:mysql://10.19.29.170:3306/fromflink152',
'table-name' = 'users',
'username' = 'root',
'password' = '29sj&170_r'
);
In mysql, I created database "fromflink152" then created the table like this way
CREATE TABLE `users` (
`id` varchar(64) NOT NULL DEFAULT '',
`name` varchar(255) DEFAULT NULL,
`age` varchar(255) DEFAULT NULL,
`status` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
)
After executed insert sql,I found 'select * from mysql_MyUserTable' can get
correct result,but ’select count(*) from mysql_MyUserTable‘ or ’select
count(id) from mysql_MyUserTable‘ ,the collect job in flink app keep restarting
again and again.The exception is:
!image-2022-10-10-15-31-34-341.png!
So I wonder which config that I missed about the table in flink or mysql side :(
