Documentation

Overview

Package schema is what a database says has been done to it.

It exists because two layers have to name the same fact and neither may own it: internal/infra/db reports the applied steps, and the system administration route reads them. A type in either one would make the other depend on it.

A Migration here is a step that was applied, which is not the db.Migration that defines a step to apply. One is a record, the other is code with an Apply function; they meet only at the id.

Types

type Migration 

type Migration struct {
	ID        string    `json:"id"`
	AppliedAt time.Time `json:"applied_at"`
}

Migration is one applied schema step.

The set of applied migrations is what tells an operator whether a database matches the binary talking to it — the question behind "we upgraded and something is wrong".

type Store 

type Store interface {
	// AppliedMigrations returns applied migrations, oldest first.
	AppliedMigrations(ctx context.Context) ([]Migration, error)
}

Store reports what has been done to the database.
