Coping with change: data schema migration in Haskell

Please log in to watch this conference skillscast.

In this talk we will introduce api-tools, a freely available Haskell library that provides a DSL for describing and performing data schema migrations on JSON structures. It allows us to write a self-documenting, human-readable schema changelog that can be validated by developers and executed during automated deployments.

Iris Connect are developing a video sharing platform that is being deployed in over a thousand schools worldwide. We'll explain how we are using api-tools to handle change in the data model at the centre of this platform. Finally, we'll reflect on a few serendipitous design decisions and on the advantages Haskell brings us.
