Challenge 53 · Backfill a column on a live table with no write lock
Build Databases · Draft
The brief
Backfill a column on a live table with no write lock.
Start it to see the workspace: the brief, the terminal, the hints and the submit step.
Where it came from
A draft with no fix attached: the project, licence, issue and fixing commit that would credit it are not all recorded yet, so it cannot be published and nothing can be graded against it. Publishing also needs a person to review it.
