usage

configuration

in config.yml for a simple cache service :

m6web_redis:
    servers:
        default:
            host:   'localhost'
            port: 6379
            reconnect: 1
    clients:
        default:
            servers:   ["default"]     # list of servers to use
            prefix:    raoul\          # prefix to use
            timeout:   2               # timeout in second
            read_write_timeout: 2      # read-write timeout in second

for a multiple clients :

m6web_redis:
    servers:
        first:
            host:   'localhost'
            port: 6379
            reconnect: 1
        second:
            host:   'xxxxxxxx'
    clients:
        default:
            servers:   ["first"]     # list of servers to use
            prefix: raoul\           # prefix to use
            timeout:   2             # timeout in second (float)
            read_write_timeout: 1.2  # read write timeout in seconds (float)
            compress: true           # compress/uncompress data sent/retrieved from redis using gzip, only method SET, SETEX, SETNX and GET are supported
        sharded:
            servers: ["first", "second"]
            prefix: raaaoul\
            timeout:   1

$this->get('m6web_redis') send the default client. this->get('m6web_redis.sharded') the sharded one.

            host:   'localhost'
            port: 6379

server configuration via wildcard

m6web_redis:
    servers:
        server1:
            host:   'localhost'
            port: 6379
        server2:
            host:   'xxxxxxxx'
    clients:
        default:
            servers:   ["server*"]     # all servers matching server*
            prefix: raoul\
            timeout:   2

event dispatcher

The event M6Web\Bundle\RedisBundle\EventDispatcher\RedisEvent is automaticly dispatched when a command is executed. Events are fired with the redis.command label.

You can customize the event name through the client configuration :

m6web_redis:
   clients:
       default:
           eventname: myEventName

session handler

# app/config/config.yml
framework:
  session:
    # ...
    handler_id: session.handler.redis

m6web_redis:
  servers:
    first:
      ip: 'localhost'
      port: 6379
  clients:
    sessions:
      servers: ["first"]
      prefix: sessions\
      timeout: 1

services:
  session.handler.redis:
    class: M6Web\Bundle\RedisBundle\Redis\RedisSessionHandler
    public:    false
    arguments:
      - '@m6web_redis.sessions'
      - 3600

dataCollector

Datacollector is available when the Symfony profiler is enabled. The collector allow you to see the following Redis data:

  • Command name
  • Execution time
  • Command arguments

overwriting base class

m6web_redis:
    clients:
        default:
            servers: ["first"]
            type: ["db"]
            timeout: 0.5
            class: \MyCompany\Redis

guzzle redis cache adapter

m6web_redis:
  clients:
    guzzlehttp:
      servers: ["first"]
      prefix: GuzzleHttp\
      class: M6Web\Bundle\RedisBundle\CacheAdapters\M6WebGuzzleHttp
      timeout: 1
