# Using this approach (instead of eg. User.each_batch) keeps the arguments
# the same for AuthorizedProjectUpdate::UserRefreshOverUserRangeWorker
# even if the user list changes, so we can deduplicate these jobs.
# Since UserRefreshOverUserRangeWorker has set data_consistency to delayed,
# a job enqueued without a delay could fail because the replica could not catch up with the primary.
# To prevent this, we start the index from `1` instead of `0` so as to ensure that
# no UserRefreshOverUserRangeWorker job is enqueued without a delay.
