public final class MigrationSet

A named group of migrations with its own history table.

An application has one, called default, which the build fills from the migration files in the project. A library that needs tables of its own registers a second set under its own name and history table, so its versions never collide with the application’s.

MigrationSet set = MigrationSet.builder("default")
        .sql("1", "create notes", "CREATE TABLE notes (id INTEGER PRIMARY KEY, body TEXT)")
        .sql("2", "add created", "ALTER TABLE notes ADD COLUMN created INTEGER")
        .build();
