# frozen_string_literal: true
# This module is designed for importers that need to create many merge
# requests quickly. When creating merge requests there are a lot of hooks
# that may run, for many different reasons. Many of these hooks (e.g. the ones
# used for rendering Markdown) are completely unnecessary and may even lead to
# transaction timeouts.
#
# To ensure importing merge requests has a minimal impact and can complete in
# a reasonable time we bypass all the hooks by inserting the row and then
# retrieving it. We then only perform the additional work that is strictly
# necessary.
