Utilities for working with memcache
:depends: - python-memcached
This library sets up a connection object for memcache, using the configuration
passed into the get_conn() function. Normally, this is __opts__. Optionally,
a profile or specific host and port may be passed in. If neither profile nor
host and port are provided, the defaults of '`127.0.0.`` and ``11211`` are
used. The following configurations are both valid:
.. code-block:: yaml
# No profile name
memcached.host: 127.0.0.1
memcached.port: 11211
# One or more profiles defined
my_memcached_config:
memcached.host: 127.0.0.1
memcached.port: 11211
Once configured, the get_conn() function is passed a set of opts, and,
optionally, the name of a profile to be used.
.. code-block:: python
import salt.utils.memcached_utils.py
conn = salt.utils.memcached_utils.get_conn(__opts__,
profile='my_memcached_config')
It should be noted that some usages of memcached may require a profile to be
specified, rather than top-level configurations. This being the case, it is
better to always use a named configuration profile, as shown above.
