A Spring Boot starter that enables rapid integration of multiple, dynamically switchable data sources in Java applications. It supports datasource grouping, read/write splitting, master-slave setups, lazy loading, encrypted credentials, and Seata-based distributed transactions.

Use cases

• connect to multiple databases in a spring boot app
• implement read-write splitting with master and slave databases
• switch datasources dynamically at runtime with annotations
• manage distributed transactions across multiple datasources with seata
• load balance queries across a group of replica databases
• encrypt database credentials in spring boot configuration
• add or remove datasources without restarting the application

When to choose

• you use Spring Boot with Mybatis or Mybatis-Plus and need multiple databases
• you want annotation-based datasource switching with read/write splitting
• you need Seata-based distributed transactions across datasources
• you want lazy datasource creation or runtime datasource management

When to avoid

• you are not on the JVM/Spring Boot stack
• you need full SQL sharding rather than simple datasource switching - consider ShardingSphere
• you need a framework-agnostic solution outside Spring's ecosystem
