We've been taught for decades that we need a complex database server to run our applications. However, these servers incur a huge performance hit for most queries and they are frequently misconfigured because of their operational complexity which can cause slowness or downtime. In this talk, I'll show you how to use a local, pure Go key/value store called BoltDB to build applications that are both simple and fast. We will see how development and deployment become a breeze once you ditch your complex database server.
