Simplify configuration file

Currently, shardingsphere configuration file need to repeat all tables’ config, event they are using same sharding rule. e.g.

spring.shardingsphere.sharding.tables.table1.actual-data-nodes=ds$->{0..1}.tab_user$->{0..1}
spring.shardingsphere.sharding.tables.table1.table-strategy.inline.sharding-column=id
spring.shardingsphere.sharding.tables.table1.table-strategy.inline.algorithm-expression=tab_user$->{id % 2}

spring.shardingsphere.sharding.tables.table2.actual-data-nodes=ds$->{0..1}.tab_user$->{0..1}
spring.shardingsphere.sharding.tables.table2.table-strategy.inline.sharding-column=id
spring.shardingsphere.sharding.tables.table2.table-strategy.inline.algorithm-expression=tab_user$->{id % 2}

in the example, table1 and table2 have exactly same sharding rule, I suggest to combine them into one group, like:

spring.shardingsphere.sharding.groups.group1.tables=table1,table2
spring.shardingsphere.sharding.groups.group1.actual-data-nodes=ds$->{0..1}.${tablename}$->{0..1}
spring.shardingsphere.sharding.groups.group1.table-strategy.inline.sharding-column=id
spring.shardingsphere.sharding.groups.group1.table-strategy.inline.algorithm-expression=${tablename}$->{id % 2}

rules:

• !SHARDING shardingTables:
  • #Sample1: all tables Sharding by item_id should be under this group tables: t_order, t_order_item

When will this feature be released?
