   ### Search before asking
   
   - [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar feature requirement.
   
   
   ### Description
   
   When the master assigns tasks by slot, it is inefficient to obtain commands by cyclically scanning the database.
   Can we use the slot to scan the database?
   
   I have an idea.
   
   such as:
   select * from t_ds_command where id % masterCount = thisMasterSlot;
   
   the masterCount and thisMasterSlot is the parameter
   
   （Associate org.apache.dolphinscheduler.server.master.runner.MasterSchedulerService）
   
   ### Use case
   
   Improve the efficiency of the master assigning tasks through slots
