NAME Plack::Middleware::Throttle::Lite::Backend::Redis - Redis-driven storage backend for Throttle-Lite VERSION version 0.03 DESCRIPTION This is implemetation of the storage backend for Plack::Middleware::Throttle::Lite. It uses redis-server to hold throttling data, automatically sets expiration time for stored keys to save memory consumption. SYNOPSYS # inside your app.psgi enable 'Throttle::Lite', backend => [ 'Redis' => { instance => 'redis.example.com:6379', database => 1, password => 'VaspUtnuNeQuiHesGapbootsewWeonJadacVebEe' } ]; OPTIONS This storage backend must be configured in order to use. All options should be passed as a hash reference. The following options are available to tune it for your needs. instance A string consist of a hostname (or an IP address) and port number (delimited with a colon) or unix socket path of the redis-server instance to connect to. Not required. Default value is 127.0.0.1:6379. Some usage examples # tcp/ip redis-servers instance => ''; # treats as '127.0.0.1:6379' instance => 'TCP:example.com:11230'; # ..as 'example.com:11230' instance => 'tcp:redis.example.org'; # ..as 'redis.example.org:6379' instance => 'redis-db.example.com'; # ..as 'redis-db.example.com:6379' instance => 'tcp:127.0.0.1'; # ..as '127.0.0.1:6379' instance => 'tcp:10.90.90.90:5000'; # ..as '10.90.90.90:5000' instance => '192.168.100.230'; # ..as '192.168.100.230:6379' instance => 'bogus:0' # ..as 'bogus:6379' (allowed > 0 and < 65536) instance => 'Inet:172.16.5.4:65000'; # ..as '172.16.5.4:65000' instance => 'bar:-100'; # ..as 'bar:6379' (allowed > 0 and < 65536) instance => 'baz:70000'; # ..as 'baz:6379' (allowed > 0 and < 65536) and so on.. # unix sockets might be passed like this instance => 'Unix:/var/foo/Redis.sock'; # this socket path '/var/foo/Redis.sock' instance => '/bar/tmp/redis/sock'; # ..as '/bar/tmp/redis/sock', instance => 'unix:/var/foo/redis.sock'; # ..as '/var/foo/redis.sock', database A redis-server database number to store throttling data. Not obligatory option. If this one omitted then value 0 will be assigned. password Password string for redis-server's AUTH command to processing any other commands. Optional. Check the redis-server manual for directive *requirepass* if you would to use redis internal authentication. reconnect A time (in seconds) to re-establish connection to the redis-server before an exception will be raised. Not required. Default value is 10 sec. every Interval (in milliseconds) after which will be an attempt to re-establish lost connection to the redis-server. Not required. Default value is 100 ms. debug Enables debug information to STDERR, including all interactions with the redis-server. Not required. Default value is 0 (disabled). METHODS redis Returns a redis connection handle. rdb A redis database number to store data. init See "ABSTRACT METHODS" in Plack::Middleware::Throttle::Lite::Backend::Abstract reqs_done See "ABSTRACT METHODS" in Plack::Middleware::Throttle::Lite::Backend::Abstract increment See "ABSTRACT METHODS" in Plack::Middleware::Throttle::Lite::Backend::Abstract BUGS Please report any bugs or feature requests through the web interface at SEE ALSO Redis Plack::Middleware::Throttle::Lite Plack::Middleware::Throttle::Lite::Backend::Abstract AUTHOR Anton Gerasimov COPYRIGHT AND LICENSE This software is copyright (c) 2013 by Anton Gerasimov.
