Guidelines
- All schema changes must be reviewed by DB Ops and/or Platform Engineering
- Add the change to the below table. All fields must be completed.
- Depending on the number of wikis and size of tables being modified, migrations can take anywhere from an hour to multiple days to fully deploy. Reviewed schema migrations should generally be added to this page and explicitly scheduled a week before the correlating software deployments.
