I believe the expiration alg defaults to volatile-lru, if that is what you are referring to.

You can put it in the individual instance hash:

    'servers' => [{'port' => '6379', 'name' => "dev_redis"}, {'port' => '6380', 'name' => "uat_redis", 'maxmemory' => ’60%’}]

You should also explore the expiration algorithm options before setting max_memory or you’ll run into a lot of errors from Redis when max_memory is reached and there aren’t any keys to evict.

I deployed the redisio cookbook and it seems to work like a charm. I did have one question when it came to max memory. How would i specify 1 instance getting 60% memory; whereas the 2-3 instance receiving 30%? Would this be done via role? Here is how I have my role setup for redis:

name "redis"
description "redis role applied to all redis servers."


run_list *%w[
  recipe[redisio::install]
  recipe[redisio::enable]
]

default_attributes({
  'redisio' => {
    'default_settings' => {'datadir' => '/etc/redis-db'},
    'servers' => [{'port' => '6379', 'name' => "dev_redis"}, {'port' => '6380', 'name' => "uat_redis"}]
  }
})


Here is the default attribute: 

'maxmemory'  => nil, - This allows the use of percentages, you must append % to the number.



I guess where and how/where would I specify devredis receives X%?
