Square’s Cash app has grown tremendously for the last few years and is currently one of the most popular mobile apps for peer-to-peer payments in the US. Originally built as a Hack Week project, it ran for a very long time on a single MySQL database.

Jon Tirsen and Karel A. Sague explain how Square scaled out the backend for its Cash app using Vitess, a database middleware for MySQL built at YouTube. With hundreds of tables, thousands of different queries, hundreds of different transactions and hundreds of thousands of lines of code, the process proved quite a challenge.

Recently my main areas of interest have been data engineering, scalability, cloud native applications and applying DevOps practices.
