require 'mongoid/database_proxy'

#
# Proxy that enables runtime swapping of the MongoDB connection. This is
# not an ideal-solution, performance-wise, as a quick check shows that
# method invocation via method_missing is about three times as slow as
# direct invocation on the object.
#
# What this does allow us to do, however, is very transparently swap out
# Mongo::Connection instances underneath Mongoid, without having to
# rewrite large portions of the codebase. In theory, this should result
# in a relatively painless connection-swapping system.
