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
