Global Memcache Configuration
-----------------------------
This document describes the configuration options available for the global swift memcache configuration
which usually lives under /etc/swift/memcache.conf.
Documentation for other swift configuration options can be found at
:doc:`index`.
An example memcache.conf configuration can be found at
etc/memcache.conf-sample in the source code repository.
There is only 1 configuration section available:
* :ref:`[memcache] <memcache_conf_memcache_section>`
.. _memcache_conf_memcache_section:

--------------------------- --------------- ---------------------------------------------
memcache_servers 127.0.0.1:11211 Comma separated list of memcached servers
ip:port or [ipv6addr]:port
memcache_max_connections 2 Max number of connections to each memcached
server per worker
connect_timeout 0.3 Timeout for connection
pool_timeout 1.0 Timeout for pooled connection
tries 3 Number of servers to retry on failures
getting a pooled connection
io_timeout 2.0 Timeout for read and writes
error_suppression_interval 60.0 How long without an error before a server's

error_suppression_limit 10 How many errors can accumulate before a
server is temporarily ignored
item_size_warning_threshold -1 If an item size ever gets above
item_size_warning_threshold then a warning
will be logged. This can be used to alert

It's an absolute size in bytes. Setting the

A value of -1 disables the warning
tls_enabled False (Optional) Global toggle for TLS usage
when comunicating with the caching servers
