# Expirable is a module that lets you easily cache
# groups of records, either across an entire record:
#   cache(Snippet) => cache(Snippet.cache_key)
# or, across a scope:
#   cache(page.blocks) => cache(page.blocks.cache_key)
#
# Why not just use `maximum(:updated_at)`?
# Because it requires 2 queries: the total count,
# and the updated_at timestamp
