What?

How do you know if you need to request a schema change? If you are changing anything in how the database is setup (columns, tables, column types, etc), you need to use this process.

Guidelines

All schema changes must be optional for your code; schema changes can take a while to propagate across the entire WMF cluster so your code should not depend on them.
All schema changes must be reviewed by DB Ops and/or Platform Engineering.
To get your schema change reviewed, open a ticket in Phabricator with all pertinent information.
Please create your ticket as soon as possible as it can take time to review and deploy the change, working around other Deployments.
We use a tracking ticket in Phabricator to list all schema change tickets.
