DynamoDB storage adapter for Rollout

This is a storage adapter for Rollout that uses DynamoDB. Rollout allows you to flip feature flags around in a sane way.

I wrote this adapter for those who either don't want to stand up a new redis instance or introduce a new single point of failure into their architecture.

Build Status

Installation

Add this line to your application's Gemfile:

gem 'rollout-dynamodb'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rollout-dynamodb

Usage

$storage = Rollout::DynamoDB::Storage.new(aws_access_key, aws_secret_key, aws_table_name, aws_region)
$rollout = Rollout.new($storage)

$rollout.active?(:chat)
# -> false
$rollout.activate(:chat)
# -> {}
$rollout.active?(:chat)
# -> true

Testing

You might want to test this code. You can get started like so:

foreman run rake

Note that there are integration tests bundled in with the specs. If you want to run them, follow the steps below, otherwise they will be skipped.

  1. Go to the AWS console for DynamoDB
  2. Create a new table, indexed by hash key named id of type String

  3. Set up the environment

    mv .env.test .env
$EDITOR .env  # set config vars
