Berater
======
[](https://codecov.io/gh/dpep/berater_rb)
All systems have limits, beyond which they tend to fail. Berater makes working within limits easy and the inevitable failures more graceful.
```ruby
require 'berater'
require 'redis'
Berater.configure do |c|
c.redis = Redis.new
end
Berater(:key, 3) do
# allow only three simultaneous requests with a concurrency limiter
end
Berater(:key, 2, interval: :minute) do
# or do work twice per minute with a rate limiter
end
```
See [documentation](https://github.com/dpep/berater_rb/wiki) for details.
