   ### Describe the feature you would like.
   There needs to be a way to define what to be done (which target names to be chosen) when sharding column is not in the SQL. Currently, as per `StandardRoutingEngine`, all available target names are returned. 
   
   As a suggestion, we can also think of 
   
   - moving this logic to the sharding algorithm itself. That means, let the sharding algorithm decide which target names to select in case there is no sharding column in the SQL 
   
   - and may be have a default behaviour, in case the sharding algorithm also does not return any target name.
