My approach is as follow:
<ul>
<li>SETEX a key (with some expiry) and the value - response of an endpoint. </li>
<li>DELETE the key when a new record is created. </li>
</ul>
Pretty basic one, what are the other techniques involved? How to decide the time for expiry of cache?
Note : I am using MySQL for persisting data

My approach is as follow:

- **SETEX **a key (with some expiry) and the value - response of an endpoint. 
- **DELETE** the key when a new record is created. 

Pretty basic one,  what are the other techniques involved? How to decide the time for expiry of cache?
