Rate limit the flow of eventsedit

This functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features.

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.
