memcache 的Ruby客户端比较常用的是(DalliCache)[https://github.com/mperham/dalli]。
连接池项目(connection_pool)[https://github.com/mperham/connection_pool]。
实战分析:
在application.rb 中添加
redis
case ENV["RACK_ENV"]
when "production"
REDIS = ConnectionPool::Wrapper.new(size: 10, timeout: 5) {
Redis.new(:driver => :synchrony, :host => "10.1.1.1", :port => 6379)
}
when "development"
REDIS = ConnectionPool::Wrapper.new(size: 10, timeout: 5) {
Redis.new(:driver => :synchrony, :host => "192.168.1.2", :port => 6379)
}
end
memcache
case ENV["RACK_ENV"]
when "production"
Dalli.logger = logger
DALLI_CACHE = ConnectionPool::Wrapper.new(size: 10, timeout: 5) {
Dalli::Client.new("10.1.1.2:11211",
{:threadsafe => true, :failover => true, :expires_in => 1.day, :compress => true})
}
when "development"
DALLI_CACHE = ConnectionPool::Wrapper.new(size: 10, timeout: 5) {
Dalli::Client.new("192.168.1.2:11211",
{:threadsafe => true, :failover => true, :expires_in => 1.day, :compress => true})
}
end
需要使用到redis或者memcache的时候,直接使用即可,并发支持最大量为配置的size的个数,每个连接的超市时间是5秒。
但是DalliCache不支持text协议的memcache集群。
如果需要集群,则只能根据文档来解决。
dalli作者的官方答复:
twemproxy does not support the memcached binary protocol.
