I have been through several variations on what you are doing. The solution which has worked best for me is to use SaltStack to control the update. It will pull your updates using git, apply as needed, and restart your servers. If you are building a new server (for testing or prototype

how to do a django data migration on a massive Postgres data table (solved)

Django migrations are run in a single transaction (if your database is capable of doing a rollback of DDL, as PostgreSQL is) so data migrations of large tables become impossible. I was able to solve this problem by having the migration run a no-wait subprocess which performs the data migration

I have learned the hard way this week that data migrations in django 1.8, as wonderful has they are, do not scale. My test data table is now sitting at about 90,000,000 rows. I was able to add a "null=True" field in an instant, as documented. Then came my attempt to fill it -- I tried using
