Standalone Persist Configuration

Class name: org.apache.shardingsphere.mode.repository.standalone.StandalonePersistRepositoryConfiguration

Attributes:

NameDataTypeDescription
typeStringType of persist repository

Notes

  1. Cluster mode deployment is recommended for production environment.
  2. The ZooKeeper registry center is recommended for cluster mode deployment.
  3. If there is configuration information in the ZooKeeper, please refer to the config information there.

Procedure

Introduce Maven Dependency

  1. <dependency>
  2.  <groupId>org.apache.shardingsphere</groupId>
  3.  <artifactId>shardingsphere-jdbc-core</artifactId>
  4.  <version>${latest.release.version}</version>
  5. </dependency>

Notice: Please change ${latest.release.version} to the actual version.

Sample

Standalone Mode

  1. ModeConfiguration modeConfig = createModeConfiguration();
  2. Map<String, DataSource> dataSourceMap = ... // Building real data sources
  3. Collection<RuleConfiguration> ruleConfigs = ... // Build specific rules
  4. Properties props = ... // Build property configuration
  5. DataSource dataSource = ShardingSphereDataSourceFactory.createDataSource(databaseName, modeConfig, dataSourceMap, ruleConfigs, props);
  7. private ModeConfiguration createModeConfiguration() {
  8.     return new ModeConfiguration("Standalone", new StandalonePersistRepositoryConfiguration("JDBC", new Properties()));
  9. }

Cluster Mode (Recommended)

  1. ModeConfiguration modeConfig = createModeConfiguration();
  2. Map<String, DataSource> dataSourceMap = ... // Building real data sources
  3. Collection<RuleConfiguration> ruleConfigs = ... // Build specific rules
  4. Properties props = ... // Build property configuration
  5. DataSource dataSource = ShardingSphereDataSourceFactory.createDataSource(databaseName, modeConfig, dataSourceMap, ruleConfigs, props);
  7. private ModeConfiguration createModeConfiguration() {
  8.     return new ModeConfiguration("Cluster", new ClusterPersistRepositoryConfiguration("ZooKeeper", "governance-sharding-db", "localhost:2181", new Properties()));
  9. }
