Version: 1.12.0

Deployment

InLong Sort is based on Apache Flink, you need to set up an Apache Flink 1.13.x or 1.15.x.

Prepare installation files​

  • InLong Sort file, Download apache-inlong-[version]-bin.tar.gz
  • Data Nodes Connectors, Download apache-inlong-[version]-sort-connectors.tar.gz
caution

Please put required Connectors jars into under FLINK_HOME/lib/ after download.
Put mysql-connector-java:8.0.21.jar to FLINK_HOME/lib/ when you use mysql-cdc-inlong connector.
If you change the Apache Flink version, you also need to change the connectors of the corresponding version.

Start an InLong Sort Job​

./bin/flink run -c org.apache.inlong.sort.Entrance apache-inlong-[version]-bin/inlong-sort/sort-dist-[version].jar \
--sql.script.file [souce-to-sink].sql
note

--sql.script.file add a SQL script file includes multi Flink SQL statements that can be separated by semicolon, support CREATE TABLE, CRETAE VIEW, INSERT INTO etc.

MySQL to PostgreSQL​

We can write following SQL script if we want to read data from MySQL and write into PostgreSQL.

  • Prepare mysql-to-postgresql.sql
 CREATE TABLE `table_1`(
    `age` INT,
    `name` STRING)
    WITH (
    'connector' = 'mysql-cdc-inlong',
    'hostname' = 'localhost',
    'port' = '3306',
    'username' = 'root',
    'password' = 'inlong',
    'database-name' = 'test',
    'scan.incremental.snapshot.enabled' = 'false',
    'server-time-zone' = 'GMT+8',
    'table-name' = 'user'
);
CREATE TABLE `table_2`(
    PRIMARY KEY (`name`) NOT ENFORCED,
    `name` STRING,
    `age` INT)
    WITH (
    'connector' = 'jdbc',
    'url' = 'jdbc:postgresql://localhost:5432/postgres',
    'username' = 'postgres',
    'password' = 'inlong',
    'table-name' = 'public.user'
);
INSERT INTO `table_2` 
    SELECT 
    `name` AS `name`,
    `age` AS `age`
    FROM `table_1`;
  • Summit job
./bin/flink run -c org.apache.inlong.sort.Entrance apache-inlong-[version]-bin/inlong-sort/sort-dist-[version].jar \
--sql.script.file mysql-to-postgresql.sql
