Rebar

A simple stress testing tool for Redis.

• Are sorted sets fast enough with 1,000,000 items?
• How big a dataset will fit in a 512 MB Redis instance?
• Should I use a thousand hashes with a thousand keys, or a million strings?

Rebar makes it easy to fill a Redis instance with sample data, so you can test performance under different database designs. Check memory usage and database creation time, or prepare a test dataset for a benchmarking exercise.

Add this line to your application's Gemfile:

gem 'rebar'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rebar

More documentation to follow. For now, here's some sample code.

require 'rubygems'
require 'rebar'
require 'redis'

Rebar.build(Redis.new) do
  # Build 10 sets with 100 members each
  sets(10) do
    members 100
  end

  # Build 10 sorted sets with 100 members each
  sorted_sets(10) do
    members 100
  end

  # Build 10 hashes with 100 keys each
  hashes(10) do
    keys 100
  end

  # Build 10 lists with 100 elements each
  lists(10) do
    elements 100
  end

  # Build 10 random key-value pairs
  strings(10)
end

By default, Rebar cleans the rebar namespace before it builds a dataset. To disable this behavior, pass :clean => false when you call Rebar.build.
