Rate Limiting by namespace

Community Support

Hey @Steven_Sun, you can provide a custom value which applies to all namespaces by updating the dynamic config. The following dynamic config will apply the limit of 2000 rps for each namespace on a single host.

frontend.namespacerps:
- value: 2000
  constraints: {}

If you want to have a different value for namespaces you can specify namespace constraints for each namespace with a different value.

frontend.namespacerps:
- value: 2000
- value: 100
  constraints:
    namespace: "namespaceA"
- value: 500
  constraints:
    namespace: "namespaceB"

The above config will limit namespaceA rps to 100 and namespaceB rps to 500. All others will use 2000 rps.

Please refer to dynamic config docs for more information.
