Imagine a high traffic website that needs post views as an algorithm to display posts on the homepage. 
This website also uses <a href="https://wordpress.org/plugins/vcaching/" rel="ugc">Varnish Caching</a>. So we need an AJAX based post views counter. 
Now imagine a minimum 5000 concurrent users browsing the website, so we can’t use the default “AJAX in Plugins” as live updates on the backend using update_post_meta will be very painful for the backend.
So what can we do ?
What if all these post views counts will be done in memory using Redis ? 
Then we run a cornjob using WP-CLI to sync the post views count in Redis to the WordPress database.
Redis Post Views was born.
