Currently the worker server is completely independent of the database. Maybe I didn't understand what you said. Would you like to express your design plan and ideas?

ATM:

public class TaskExecuteThread implements Runnable, Delayed {
    ...
     @Override
      public void run() {
           ...
           TaskChannel taskChannel = taskPluginManager.getTaskChannelMap().get(taskExecutionContext.getTaskType());
           ...
      }
}

@Component
public class TaskPluginManager {
    ....
     private final PluginDao pluginDao;
     ....
}

In addition, due to the dependence on the dolphinscheduler-service package, spring will automatically inject the datasource
