Public Description

Yann: "We need to delete this long_name field from the User model - it's not been used for a long time." Nick: "I'm in if you are. Lets go exploring!"

Follow Yann and Nick as they follow this journey for removing a database column from start to finish - how hard can it be?

Privage description

We would like to structure the talk as a discussion between two engineers, rather than a solo speaker. The reason is that we want to explain the various design decisions we were making, and also make it more engaging for the audience.
