Migration file format reference (config v2)

Introduction

With config v2, the migrations files generated by the CLI are pure SQL files.

Note

For config v1, see Migration file format reference (config v1)

Migration filename format

Each migration file has the following format:

<version>_<name>.{up|down}.sql

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.
