About 4 months ago, I was given the opportunity to architect a greenfield react project with staggering amounts of complexity. I had only heard of hooks in passing before this project, but knew they were the new hotness in the world of front-end react development. Hooks could purportedly remove the need for redux as a state management tool, cut boilerplate code in half, and improve performance significantly. I thought to myself, "These claims are obviously exaggerated. Surely a production grade application with a feature rich front-end needs class components, right?"

Serverless is one of the latest buzzwords flying around in technology circles. It's hard to keep up with what it means and, more importantly, how it can be used. I spent the last few days at Serverless Conf 19 in NYC and here are some important takeaways.

Many of us work with databases occasionally or daily. And I bet all of us are being told that to speed up the query speed, we can create and use index for tables. But probably few of us know how index is actually implemented under the hood, myself included. So I started developing an interest in this topic a while ago and wanted to know, at least at a high level, what makes database indexing happens.

In this post, we’ll walk through writing this as a serverless function and seeing it’s benefits of simplicity, maintainability, scalability and cost-effectiveness.
