Usage for SQL API
- Deploy InLong Sort
- Create Data Node
The example shows how to create a MySQL Load Node in Flink SQL Client and load data to it.
-- Creates a MySQL Extract Node
CREATE TABLE mysql_extract_node (
id INT NOT NULL,
name STRING,
age INT,
weight DECIMAL(10,3),
PRIMARY KEY(id) NOT ENFORCED
) WITH (
'connector' = 'mysql-cdc-inlong',
'hostname' = 'YourHostname',
'port' = '3306',
'username' = 'YourUsername',
'password' = 'YourPassword',
'database-name' = 'YourDatabaseName',
'table-name' = 'YourTableName'
);
-- Creates a MySQL Load Node
CREATE TABLE mysql_load_node (
id INT NOT NULL,
name STRING,
age INT,
weight DECIMAL(10,3),
PRIMARY KEY(id) NOT ENFORCED
) WITH (
'connector' = 'jdbc-inlong',
'url' = 'jdbc:mysql://YourHostname:3306/YourDatabaseName',
'username' = 'YourUsername',
'password' = 'YourPassword',
'table-name' = 'YourTableName'
);
INSERT INTO mysql_load_node SELECT id, name, age, weight FROM mysql_extract_node;
