How to make my program asynchronous with asyncio in Python 3.7? - python-3.x

Question

My code is to search the data from the ES database And add some new data in the database . I used to run in a single process, but this is too inefficient, so I want to add asyncio to my code. How can I do it? I removed the URL of my ES data based on security considerations. is there anyone can help me?
