ratio #

Description #

The ratio filter is used to forward normal traffic to another flow proportionally. It can implement canary release, traffic migration and export, or switch some traffic to clusters of different versions for testing.

Configuration Example #

A simple example is as follows:

flow:
  - name: ratio_traffic_forward
    filter:
      - ratio:
          ratio: 0.1
          flow: hello_world
          continue: true

Parameter Description #

Name	Type	Description
ratio	float	Proportion of traffic to be migrated
flow	string	New traffic processing flow
continue	bool	Whether to continue the previous flow after traffic is migrated. The gateway returns immediately after it is set to `false`. The default value is `false`.
