# frozen_string_literal: true

# collection_cache_versioning was added in Rails 6.0. It performs a
# SELECT COUNT(*), MAX(updated_at) which will have an unnecessary ORDER BY RANDOM()
# applied to it. That shouldn't hurt anything. This is a simple way to both
# cover that important code and ensure Unreliable works correctly with
# aggregate SELECTs.
