Upgrading an EventStore

The CHANGELOG is used to indicate when a schema migration is required for a given version of the EventStore.

You can upgrade an existing EventStore database using the following mix task:

$ mix event_store.migrate

Or use mix event_store.migrate -e MyApp.EventStore to specify an event store as an argument.

Run this command each time you upgrade; it is safe to run multiple times.

You must stop your application to apply an upgrade. It is always worth taking a full backup of the EventStore database before applying an upgrade.

Creating an EventStore, using the mix event_store.create task, will always use the latest database schema.
