title: Airflow transfer data between tasks without storing data in between stages
body: <p>I would like to know how to transfer data between tasks without storing them in between. 
  Attached <a href="https://i.stack.imgur.com/YpOjP.png" rel="noreferrer">image</a> one can find the flow of tasks. As of now I am storing the output csv files of each task as a file in my local machine and fetching this csv file again as an input to next task. I wanted to know if there is any otherway to pass data between tasks without storing it after each task. I researched a bit and came across <strong>Xcoms</strong>. I wanted to make sure if <strong>Xcoms</strong> are the right way to achieve this or am I wrong. I could not find any practical examples. Any help is appreciated as I am just a newbie in airflow started couple of days</p>
