Amazon Redshift adapter for ActiveRecord 5 (Rails 5). I cloned the project from aamine/activerecord4-redshift-adapter.
The Redshift driver for ActiveRecord4 already exists at: https://github.com/aamine/activerecord4-redshift-adapter, and the one for ActiveRecord3 exists at https://github.com/fiksu/activerecord-redshift-adapter.
There are some differences for AR5, and this driver tries to stay compatible with those.
If anybody writes a better Redshift driver which works with ActiveRecord 5, and maintains it, we would happily switch to that.
For Rails 5, write following in Gemfile:
gem 'activerecord5-redshift-adapter'
In database.yml
development:
  adapter: redshift
  host: your_cluster_name.at.redshift.amazonaws.com
  port: 5439
  database: your_db
  username: your_user
  password: your_password
  encoding: utf8
  pool: 3
  timeout: 5000
