Overview

Hands-on with expand-and-contract migrations, backfills and safe rollbacks on a real dataset. Bring a laptop with Docker installed; we send the container image the week before so the first half-hour is not spent on hotel Wi-Fi.

Ruth Achterberg leads four tight blocks in a bright second-floor room on Linienstraße, with two assistants walking the tables. You will rename a busy column without a lock, backfill forty million rows in batches, and then deliberately break a deploy so you can practise the rollback while the clock is running.

Thirty seats at long shared tables, power at every place, coffee and pretzels at the break. You leave with the scripts, a checklist you can paste into your own runbook and a certificate of attendance for your manager.
