Once your cache is configured, you've got two choices for how to store data in
|
||||
the cache:
|
||||
|
||||
* Set :setting:`SESSION_ENGINE` to
|
||||
``"django.contrib.sessions.backends.cache"`` for a simple caching session
|
||||
store. Session data will be stored directly your cache. However, session
|
||||
data may not be persistant: cached data can be evicted if the cache fills
|
||||
data may not be persistent: cached data can be evicted if the cache fills
|
||||
up or if the cache server is restarted.
|
||||
|
||||
* For persistant, cached data, set :setting:`SESSION_ENGINE` to
|
||||
* For persistent, cached data, set :setting:`SESSION_ENGINE` to
|
||||
``"django.contrib.sessions.backends.cached_db"``. This uses a
|
||||
write-through cache -- every write to the cache will also be written to
|
||||
the database. Session reads only use the database if the data is not
|
||||
already in the cache.
|
||||
|
||||
Both session stores are quite fast, but the simple cache is faster because it
|
||||
disreguards persistance. In most cases, the ``cached_db`` backend will be fast
|
||||
disregards persistence. In most cases, the ``cached_db`` backend will be fast
|
||||
enough, but if you need that last bit of performance, and are willing to let
|
||||
session data be expunged from time to time, the ``cache`` backend is for you.
