Migration file format reference


The config V3 migrations files generated by the CLI are pure SQL files.

Migration filename format

Each migration file has the following format:


A version which is the Unix timestamp in nanoseconds when the file was created is the first part. Followed by a name which is either manually added or auto-generated by the console. The next part indicates what step this is. If it is up, it means that this is the forward step, e.g. creating a table. The down indicates that it is the corresponding rollback step.

Migration file format

A migration SQL file can contain SQL statements which are executed on the apply step of the migration. There can be an up migration and a down migration file.
