# Since audit_events is a partitioned table, we need to prepare the index
# for each partition individually. We can't use the `prepare_async_index`
# method directly because it will try to prepare the index for the whole
# table, which will fail.
# In a future migration after this one, we will create the index on the
# parent table itself.
# TODO: Issue for future migration https://gitlab.com/gitlab-org/gitlab/-/issues/411129
