mawer111 opened a new issue #5487:

## Question
if not config table rule for tabe A , just set default database sharding strategy, the default database strategy is work?
my situation： every table sharding in some db, but only some of them sharding in different tables,Is it possible to set a default database sharing strategy for all table？
at the last，Thanks for developer

DefaultDatasourceShardingStrategy is remove in master now.
Under the design principles, each table that you need to control by shardingsphere, should be configured in config files.

and i think the annotation meta code is a good way to solve config problem.

after read source code,I know DefaultDatasourceShardingStrategy wouldn't work without config table sharding rule
If table a isnt config with a sharding rule,
if config one defaultDatasource name,it will route by SharedingDefaultDatabaseRouting Engine
otherwires,will route by ShardingUnicastRoutingEngine , in ShardingRouteEngineFactory
ShardingUnicastRoutingEngine will route to a random datasource in datasource names
