moduleFasterCacheKeys# A faster version of Rails' "cache_key" method.## Rails' default "cache_key" method uses all kind of complex logic to figure# out the cache key. In many cases this complexity and overhead may not be# needed.## This method does not do any timestamp parsing as this process is quite# expensive and not needed when generating cache keys. This method also relies# on the table name instead of the cache namespace name as the latter uses# complex logic to generate the exact same value (as when using the table# name) in 99% of the cases.defcache_key"#{self.class.table_name}/#{id}-#{read_attribute_before_type_cast(:updated_at)}"endend
