Rate limiting rules

Lyft open-sourced its rate-limiting component [12]. We will peek inside of the component and look at some examples of rate-limiting rules:

domain: messaging
descriptors:
- key: message_type
  Value: marketing
  rate_limit:
   unit: day
   requests_per_unit: 5

In the above example, the system is configured to allow a maximum of 5 marketing messages per day. Here is another example:

domain: auth
descriptors:
- key: auth_type
  Value: login
  rate_limit:
   unit: minute
   requests_per_unit: 5

This rule shows that clients are not allowed to login more than 5 times in 1 minute. Rules are generally written in configuration files and saved on disk.
