Introduction

This module is the jdbc registry plugin module, this plugin will use jdbc as the registry center. Will use the database configuration same as DolphinScheduler in api'yaml default.

How to use

  1. Initialize the database table
  • If you use Mysql you can directly execute the sql script src/main/resources/mysql_registry_init.sql.

  • If you use Postgresql you can directly execute the sql script src/main/resources/postgresql_registry_init.sql.

  1. Change the config

You need to set the registry properties in master/worker/api's appplication.yml

registry:
  type: jdbc

After do this two steps, you can start your DolphinScheduler cluster, your cluster will use mysql as registry center to store server metadata.

NOTE: You need to add mysql-connector-java.jar into DS classpath if you use mysql database, since this plugin will not bundle this driver in distribution. You can get the detail about Initialize the Database.

Optional configuration

registry:
  type: jdbc
  # Used to schedule refresh the ephemeral data/ lock.
  term-refresh-interval: 2s
  # Used to calculate the expire time,
  # e.g. if you set 2, and latest two refresh error, then the ephemeral data/lock will be expire.
  term-expire-times: 3

Use different database configuration for jdbc registry center

You need to set the registry properties in master/worker/api's appplication.yml

Use Mysql as registry center

registry:
  type: jdbc
  term-refresh-interval: 2s
  term-expire-times: 3
  hikari-config:
    jdbc-url: jdbc:mysql://127.0.0.1:3306/dolphinscheduler
    username: root
    password: root
    maximum-pool-size: 5
    connection-timeout: 9000
    idle-timeout: 600000

Use Postgresql as registry center

registry:
  type: jdbc
  term-refresh-interval: 2s
  term-expire-times: 3
  hikari-config:
    jdbc-url: jdbc:postgresql://localhost:5432/dolphinscheduler
    username: root
    password: root
    maximum-pool-size: 5
    connection-timeout: 9000
    idle-timeout: 600000
