# This Gist is an alternative to ndb.get_multi which is a lot faster in some circumstances.
# For example, fetching 500 small entities with 90% hit rate is 3x faster than ndb,
# based on my tests in App Engine production environment (F1).
# In general it is worthwhile when fetching a large number of small entities, with >50% memcache hit rate.
# For any keys not in memcache, it falls back on a normal ndb.get_multi

# The code is based on the original ndb.context code, but avoids the task queue overhead.
