   > Hi how about sharding rule configuration?
   only split db 
      <sharding:standard-strategy id="databaseStrategy" sharding-column="tenant_id" precise-algorithm-ref="commonDBShardingAlgorithm"/>
     <sharding:table-rule logic-table="stock_age" actual-data-nodes="ds_ms$->{0..1}.stock_age" database-strategy-ref="databaseStrategy"  />
     <sharding:master-slave-rules>
                   <sharding:master-slave-rule id="ds_ms0" master-data-source-name="ds_0" slave-data-source-names="ds_0_slave_0, ds_0_slave_1" strategy-ref="roundStrategy" />
                   <sharding:master-slave-rule id="ds_ms1" master-data-source-name="ds_1" slave-data-source-names="ds_1_slave_0, ds_1_slave_1" strategy-ref="roundStrategy" />
               </sharding:master-slave-rules>
   
   the commonDBShardingAlgorithm is mapping by tenant_id, like 
     map.put("tenant_id","the suffix of dbname")
     map.put("CP0000028","1");
     map.put("CP0000030","1");
