Redis Marshaling

If you have time consuming method in your app that you call frequently, chances are that you’d like to cache it. Redis is great key-value store that can be used for this purpose. However, redis only store string values. In order to store other kinds of objects, you’ll have to use marshaling.

There is a built-in ruby class called Marshal that does the job well. The only thing you have to do is to call Marshal.dump method and pass it an object. The exact opposite is the Marshal.load method.

I’ve created helper method for easier integration with Redis. Here is how it looks:

module RedisHelper

Redis setup hints

    We suggest deploying Redis using the Linux operating system. Redis is also tested heavily on OS X, and tested from time to time on FreeBSD and OpenBSD systems. However Linux is where we do all the major stress testing, and where most production deployments are working.
    Make sure to set the Linux kernel overcommit memory setting to 1. Add vm.overcommit_memory = 1 to /etc/sysctl.conf and then reboot or run the command sysctl vm.overcommit_memory=1 for this to take effect immediately.
    Make sure to disable Linux kernel feature transparent huge pages, it will affect greatly both memory usage and latency in a negative way. This is accomplished with the following command: echo never > sys/kernel/mm/transparent_hugepage/enabled.
    Make sure to setup some swap in your syst
