sco / cache_cache.rb

Created March 26, 2009 12:41

	require 'memcached'

	# Provides a hybrid of memoization and memcacheing. Designed for storing an entire (small)
	# table in memory, in every instance of the app. Works well for reference-type tables
	# (e.g., Category) which won't ever get big or change often, but are read-heavy. This
	# allows you to avoid joins, but also avoid the n+1 queries antipattern.
	#
	# A pure memoization solution fails when the data does change -- all app instances have
	# to be restarted for the in-memory caches to be correct. A pure memcached solution solves
	# that, but requires a largish amount of data to be retrieved from memcached for every
