title: Airflow dynamic dag creation
body: <p>Someone please tell me whether a DAG in airflow is just a graph (like a placeholder) without any actual data (like arguments) associated with it OR a DAG is like an instance (for a fixed argument)?</p>
  
  <p>I want a system where the set of operations to perform (given a set of arguments) are fixed. But this input will be different everytime the set of operations are run. In simple terms, the pipeline is the same but the arguments to the pipeline will be different everytime it is run. </p>
  
  <p>I want to know how to configure this in airflow? Should I create a new DAG for every new set of arguments? or any other method?</p>
  
  <p>In my case, the graph is the same but want to run it on different data (from different users) as they come. So, should I create a new DAG everytime for new data?</p>
