   Hi community,
   
   Now, readwrite-splitting static and dynamic configuration are together, we 
think this is not clear enough. So, we plan to split the readwrite-splitting 
static and dynamic configuration to SPI interfaces.
   
   `Before adjustment configuration :`
   
   ```
   schemaName: readwrite_splitting_db
   
   dataSources:
     write_ds:
       url: 
jdbc:mysql://127.0.0.1:3306/demo_write_ds?serverTimezone=UTC&useSSL=false
       username: root
       password: 123456
       connectionTimeoutMilliseconds: 30000
       idleTimeoutMilliseconds: 60000
       maxLifetimeMilliseconds: 1800000
       maxPoolSize: 50
       minPoolSize: 1
     read_ds_0:
       url: 
jdbc:mysql://127.0.0.1:3306/demo_read_ds_0?serverTimezone=UTC&useSSL=false
       username: root
       password: 123456
       connectionTimeoutMilliseconds: 30000
       idleTimeoutMilliseconds: 60000
       maxLifetimeMilliseconds: 1800000
       maxPoolSize: 50
       minPoolSize: 1
