JDBC Connector Introduction

The JDBC Connector is contributed by the community and supports both reading and writing operations.

Syntax

CREATE TABLE jdbc_table (
  id BIGINT,
  name VARCHAR,
  age INT
) WITH (
	type='jdbc',
    geaflow.dsl.jdbc.driver = 'org.h2.Driver',
    geaflow.dsl.jdbc.url = 'jdbc:h2:mem:testdb;DB_CLOSE_DELAY=-1',
    geaflow.dsl.jdbc.username = 'h2_user',
    geaflow.dsl.jdbc.password = 'h2_pwd',
    geaflow.dsl.jdbc.table.name = 'source_table'
);

Options

Key	Required	Description
geaflow.dsl.jdbc.driver	true	The JDBC driver.
geaflow.dsl.jdbc.url	true	The database URL.
geaflow.dsl.jdbc.username	true	The database username.
geaflow.dsl.jdbc.password	true	The database password.
geaflow.dsl.jdbc.table.name	true	The table name.
geaflow.dsl.jdbc.partition.num	false	The JDBC partition number, default 1.
geaflow.dsl.jdbc.partition.column	false	The JDBC partition column. Default value is 'id'.
geaflow.dsl.jdbc.partition.lowerbound	false	The lowerbound of JDBC partition, just used to decide the partition stride, not for filtering the rows in table.
geaflow.dsl.jdbc.partition.upperbound	false	The upperbound of JDBC partition, just used to decide the partition stride, not for filtering the rows in table.

Example

set geaflow.dsl.jdbc.driver = 'org.h2.Driver';
set geaflow.dsl.jdbc.url = 'jdbc:h2:mem:testdb;DB_CLOSE_DELAY=-1';
set geaflow.dsl.jdbc.username = 'h2_user';
set geaflow.dsl.jdbc.password = 'h2_pwd'; 

CREATE TABLE jdbc_source_table (
  id BIGINT,
  name VARCHAR,
  age INT
) WITH (
	type='jdbc',
    geaflow.dsl.jdbc.table.name = 'source_table',
);

CREATE TABLE jdbc_sink_table (
  id BIGINT,
  name VARCHAR,
  age INT
) WITH (
	type='jdbc',
    geaflow.dsl.jdbc.table.name = 'sink_table'
);

INSERT INTO jdbc_sink_table
SELECT * FROM jdbc_source_table;
