-  # Set this constant to true if this migration requires downtime.
-  DOWNTIME = false
-
-  # When a migration requires downtime you **must** uncomment the following
-  # constant and define a short and easy to understand explanation as to why the
-  # migration requires downtime.
-  # DOWNTIME_REASON = ''
-
-  # When using the methods "add_concurrent_index", "remove_concurrent_index" or
-  # "add_column_with_default" you must disable the use of transactions
-  # as these methods can not run in an existing transaction.
-  # When using "add_concurrent_index" or "remove_concurrent_index" methods make sure
-  # that either of them is the _only_ method called in the migration,
-  # any other changes should go in a separate migration.
-  # This ensures that upon failure _only_ the index creation or removing fails
-  # and can be retried or reverted easily.
-  #
-  # To disable transactions uncomment the following line and remove these
-  # comments:
-  # disable_ddl_transaction!
