+
+Purpose
+-------
 
 Simple Django cache backend for Amazon ElastiCache (memcached based). It uses
-`pylibmc <http://github.com/lericson/pylibmc>`_ and sets up a connection to each
+`pymemcache <https://github.com/pinterest/pymemcache>`_ and sets up a connection to each
 node in the cluster using
 `auto discovery <http://docs.aws.amazon.com/AmazonElastiCache/latest/UserGuide/AutoDiscovery.html>`_.
-
+Originally forked from `django-elasticache <https://github.com/gusdan/django-elasticache>`_.
 
 Requirements
 ------------
 
-* pylibmc
-* Django 1.5+.
-
-It was written and tested on Python 2.7 and 3.4.
+* pymemcache
+* Django>=1.8
 
 Installation
 ------------
 
-Get it from `pypi <http://pypi.python.org/pypi/django-elasticache>`_::
-
-    pip install django-elasticache
-
-or `github <http://github.com/gusdan/django-elasticache>`_::
-
-    pip install -e git://github.com/gusdan/django-elasticache.git#egg=django-elasticache
+Get it from `pypi <http://pypi.python.org/pypi/django-elastipymemcache>`_::
 
+    pip install django-elastipymemcache
 
 Usage
 -----
@@ -34,95 +47,16 @@ Your cache backend should look something like this::
 
     CACHES = {
         'default': {
-            'BACKEND': 'django_elasticache.memcached.ElastiCache',
-            'LOCATION': 'cache-c.draaaf.cfg.use1.cache.amazonaws.com:11211',
-            'OPTIONS' {
-                'IGNORE_CLUSTER_ERRORS': [True,False],
-            },
-        }
-    }
-
-By the first call to cache it connects to cluster (using ``LOCATION`` param),
-gets list of all nodes and setup pylibmc client using full
-list of nodes. As result your cache will work with all nodes in cluster and
-automatically detect new nodes in cluster. List of nodes are stored in class-level
-cached, so any changes in cluster take affect only after restart of working process.
-But if you're using gunicorn or mod_wsgi you usually have max_request settings which
-restart process after some count of processed requests, so auto discovery will work
-fine.
-
-The ``IGNORE_CLUSTER_ERRORS`` option is useful when ``LOCATION`` doesn't have support
-for ``config get cluster``. When set to ``True``, and ``config get cluster`` fails,
-it returns a list of a single node with the same endpoint supplied to ``LOCATION``.
-
-Django-elasticache changes default pylibmc params to increase performance.
-
-Another solutions
------------------
-
-ElastiCache provides memcached interface so there are three solution of using it:
-
-1. Memcached configured with location = Configuration Endpoint
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-In this case your application
-will randomly connect to nodes in cluster and cache will be used with not optimal
-way. At some moment you will be connected to first node and set item. Minute later
-you will be connected to another node and will not able to get this item.
-
- ::
-
-    CACHES = {
-        'default': {
-            'BACKEND': 'django.core.cache.backends.memcached.PyLibMCCache',
-            'LOCATION': 'cache.gasdbp.cfg.use1.cache.amazonaws.com:11211',
-        }
-    }
-
-
-2. Memcached configured with all nodes
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-It will work fine, memcache client will
-separate items between all nodes and will balance loading on client side. You will
-have problems only after adding new nodes or delete old nodes. In this case you should
-add new nodes manually and don't forget update your app after all changes on AWS.
-
- ::
-
-    CACHES = {
-        'default': {
-            'BACKEND': 'django.core.cache.backends.memcached.PyLibMCCache',
-            'LOCATION': [
-                'cache.gqasdbp.0001.use1.cache.amazonaws.com:11211',
-                'cache.gqasdbp.0002.use1.cache.amazonaws.com:11211',
-            ]
-        }
-    }
-
-
-3. Use django-elasticache
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-It will connect to cluster and retrieve ip addresses
-of all nodes and configure memcached to use all nodes.
-
- ::
-
-    CACHES = {
-        'default': {
-            'BACKEND': 'django_elasticache.memcached.ElastiCache',
-            'LOCATION': 'cache-c.draaaf.cfg.use1.cache.amazonaws.com:11211',
+            'BACKEND': 'django_elastipymemcache.memcached.ElastiPyMemCache',
+            'LOCATION': '[configuration endpoint]:11211',
+            'OPTIONS': {
+              'cluster_timeout': 1, # its used when get cluster info
+              'ignore_exc': True, # pymemcache Client params
+              'ignore_cluster_errors': True, # ignore get cluster info error
+            }
         }
     }

-Difference between setup with nodes list (django-elasticache) and
-connection to only one configuration Endpoint (using dns routing) you can see on
-this graph:
