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
