Description #

The request_user_limiter filter is used to control traffic by username.

Configuration Example #

A configuration example is as follows:

flow:
  - name: rate_limit_flow
    filter:
      - request_user_limiter:
          user:
            - elastic
            - medcl
          max_requests: 256
#          max_bytes: 102400 #100k
          action: retry # retry or drop
#          max_retry_times: 1000
#          retry_interval: 500 #100ms
          message: "you reached our limit"
