In this segment we explore how you can use traditional blocking operations in the asynchronous and non-blocking Vert.x Verticles.
We also talk about Currying (https://en.wikipedia.org/wiki/Currying) with Vert.x Handlers.
Finally, we discuss using FlywayDB (https://flywaydb.org/) to do database schema migrations.
