# frozen_string_literal: true
# This is workaround for
# https://gitlab.com/gitlab-org/gitlab/-/issues/388253. During a
# zero-downtime upgrade, duplicate jobs cookies can fail to get deleted.
# This post-deployment migration deletes all such cookies. This can
# cause some jobs that normally would have been deduplicated to twice
# instead of once.
