Rate limit the flow of events

The rate_limit processor limits the throughput of events based on the specified configuration.

In the current implementation, rate-limited events are dropped. Future implementations may allow rate-limited events to be handled differently.

processors:
- rate_limit:
   limit: "10000/m"

processors:
- rate_limit:
   fields:
   - "cloudfoundry.org.name"
   limit: "400/s"

processors:
- if.equals.cloudfoundry.org.name: "acme"
  then:
  - rate_limit:
      limit: "500/s"

The following settings are supported:

limit

The rate limit. Supported time units for the rate are s (per second), m (per minute), and h (per hour).

fields

(Optional) List of fields. The rate limit will be applied to each distinct value derived by combining the values of these fields.
