Class: swift::memcache

This class creates a memcache configuration file

Parameters

memcache_servers

You can use this single conf file instead of having memcache_servers set in several other conf files under [filter:cache] for example. You can specify multiple servers separated with commas, as in: 10.1.2.3:11211,10.1.2.4:11211 Default to [‘127.0.0.1:11211’]

memcache_serialization_support

Sets how memcache values are serialized and deserialized: 0 = older, insecure pickle serialization 1 = json serialization but pickles can still be read (still insecure) 2 = json serialization only (secure and the default) To avoid an instant full cache flush, existing installations should upgrade with 0, then set to 1 and reload, then after some time (24 hours) set to 2 and reload. In the future, the ability to use pickle serialization will be removed. Default to $facts

memcache_max_connections

Sets the maximum number of connections to each memcached server per worker Default to $facts

connect_timeout

Timeout for connection Default to $facts

pool_timeout

Timeout for pooled connection Default to $facts

tries

number of servers to retry on failures getting a pooled connection Default to $facts

io_timeout

Timeout for read and writes Default to $facts
