title: how many tasks can be scheduled in a single airflow dag?
body: <p>I am completely new to airflow, and couldn't find anywhere that how many tasks can be scheduled in a single airflow DAG. And <strong>what can be the maximum size of each task.</strong><br><br>
  I want to schedule a task which should be able to handle millions of queries and identify its type and schedule the next task according to the type of query.<br><br>
  Read complete documentation but couldn't find it</p>
