There was a problem hiding this comment.
This is safe to deploy any time, then pick a time after to apply the production index, right?

Correct, adding the column should be instant. Adding the index should also be pretty harmless, but probably best to do after a DTP and after peak hours just to be safe. |

This is the first PR in a series of PRs to migrate our existing channel token system for projects to unique identifiers. This PR adds an indexed UUID column to the projects table.
In production, the Projects table has nearly 1.4 billion rows. Because of this, the index will need to be manually added. When tested on a production-cloned adhoc, creating the index took 1hr and 45min. During this time, I was able to make updates to projects directly in the console, as well as create and edit projects via the UI.
The command to add the index in
production-console:Links
Testing story
Tested the migration on a production-cloned adhoc.
Deployment strategy
Once this migration has been deployed to all environments, we will need to manually create the index on production using the command above. This should be done after peak hours, after a deploy, and is expected to take less than 2 hours.
Follow-up work
After the UUID column is created, we will need to start using it! The plan is to do this over a series of PRs.
Privacy and Security
This PR is the first step in further securing our projects.
