Orchestration

Using orchestration requires designating a registry center, in which all the configurations are saved. Users can either use local configurations to cover registry center configurations or read configurations from registry center.

Not Use Spring

Introduce Maven Dependency

<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>sharding-jdbc-orchestration</artifactId>
    <version>${sharding-sphere.version}</version>
</dependency>
<!--If you want to use zookeeper, please use the artifactId below.-->
<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>sharding-orchestration-reg-zookeeper-curator</artifactId>
    <version>${sharding-sphere.version}</version>
</dependency>

Rule Configuration Based on Java

    // Configure dataSourceMap and shardingRuleConfig
    // ...

    // Configure registry center
    RegistryCenterConfiguration regConfig = new RegistryCenterConfiguration("zookeeper");
    regConfig.setServerLists("localhost:2181");
    regConfig.setNamespace("sharding-sphere-orchestration");

    // Configure orchestration
    OrchestrationConfiguration orchConfig = new OrchestrationConfiguration("orchestration-sharding-data-source", regConfig, false);

    // Get data source
    DataSource dataSource = OrchestrationShardingDataSourceFactory.createDataSource(dataSourceMap, shardingRuleConfig, new Properties(), orchConfig);

Rule Configuration Based on Yaml

Or use Yaml to configure, similar as above configurations:

orchestration:
  name: orchestration-sharding-data-source
  overwrite: false
  registry:
    type: zookeeper
    serverLists: localhost:2181
    namespace: sharding-sphere-orchestration

    DataSource dataSource = YamlOrchestrationShardingDataSourceFactory.createDataSource(yamlFile);

Using Spring

Introduce Maven Dependency

<!-- for spring boot -->
<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>sharding-jdbc-orchestration-spring-boot-starter</artifactId>
    <version>${sharding-sphere.version}</version>
</dependency>

<!--If you want to use zookeeper, please add the Maven below.-->
<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>sharding-orchestration-reg-zookeeper-curator</artifactId>
    <version>${sharding-sphere.version}</version>
</dependency>

<!-- for spring namespace -->
<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>sharding-jdbc-orchestration-spring-namespace</artifactId>
    <version>${sharding-sphere.version}</version>
</dependency>

    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>sharding-orchestration-reg-zookeeper-curator</artifactId>
    <version>${sharding-sphere.version}</version>
</dependency>

Rule Configuration Based on Spring Boot

spring.shardingsphere.orchestration.name=orchestration-sharding-data-source
spring.shardingsphere.orchestration.overwrite=false
spring.shardingsphere.orchestration.registry.type=zookeeper
spring.shardingsphere.orchestration.registry.server-lists=localhost:2181
spring.shardingsphere.orchestration.registry.namespace=sharding-jdbc-orchestration
