Functions

• create_migration_chain 🔒
  Creates a migration chain from start to goal. The chain is chosen to be the shortest possible. If there are multiple shortest paths, any of them is chosen. This method will use the pre-defined migrations map.
• create_migration_chain_from_migrations 🔒
  Same as create_migration_chain, but uses any provided migrations map.
• temporary_db_name 🔒
  Returns the name of the temporary database that will be created during the migration.

Type Aliases
