Overview

The migration recorder class.

The migration recorder is responsible for recording the fact that specific migrations where applied to the DB. It does so by creating a "migration record" for each of the applied migration that is persisted in the marten_migrations table of the current database. The whole migration mechanism relies on the recorder in order to know which migrations where previously applied for each installed application.
