原文:
A final point about Memcached is that memory-based caching has one important disadvantage.
Because the cached data is stored only in memory, the data will be lost if your server
crashes. Clearly, memory isnt intended for permanent data storage, so dont rely on
memory-based caching as your only data storage. Without a doubt, *none* of the Django
caching back-ends should be used for permanent storagetheyre all intended to be solutions
for caching, not storagebut we point this out here because memory-based caching is
particularly temporary.
