Usage for SQL API

We need several steps to setup a Flink cluster with the provided connector.

  1. Setup a Flink cluster with version 1.13.5 and Java 8+ installed.
  2. Download and the Sort Connectors jars from the Downloads page (or build yourself).
  3. Put the Sort Connectors jars under FLINK_HOME/lib/.
  4. Restart the Flink cluster.

The example shows how to create a MySQL Extract Node in Flink SQL Client and execute queries on it.

-- Creates a MySQL Extract Node
CREATE TABLE mysql_extract_node (
name STRING,
age INT,
weight DECIMAL(10,3),
) WITH (
'connector' = 'mysql-cdc-inlong',
'hostname' = 'YourHostname',
'port' = '3306',
'username' = 'YourUsername',
'password' = 'YourPassword',
'database-name' = 'YourDatabaseName',
'table-name' = 'YourTableName'

SELECT id, name, age, weight FROM mysql_extract_node;
