Chapter 1. Ordering Migrations

Migrate all remote regions before migrating the global region. This requirement ensures prevention of missed schema states and instances of inability to replicate changes from a remote region.

Recovering from Migration Errors

Migration error messages will appear when bin/rake db:migrate is executed on the global region before migrating remote regions.

Example Error Message:

Waiting for remote region X to run migration 2012154125454

Press Ctrl-C from the command line to interrupt the application.

Important

Do not run evmserverd if a database is in a partially migrated state.
