Chapter 16. Configuring the DPA with client burst and QPS settings


The burst setting determines how many requests can be sent to the velero server before the limit is applied. After the burst limit is reached, the queries per second (QPS) setting determines how many additional requests can be sent per second.

You can set the burst and QPS values of the velero server by configuring the Data Protection Application (DPA) with the burst and QPS values. You can use the dpa.configuration.velero.client-burst and dpa.configuration.velero.client-qps fields of the DPA to set the burst and QPS values.

Prerequisites

  • You have installed the OADP Operator.

Procedure

  • Configure the client-burst and the client-qps fields in the DPA as shown in the following example:

    Example Data Protection Application

    apiVersion: oadp.openshift.io/v1alpha1
    kind: DataProtectionApplication
    metadata:
      name: test-dpa
      namespace: openshift-adp
    spec:
      backupLocations:
        - name: default
          velero:
            config:
              insecureSkipTLSVerify: "true"
              profile: "default"
              region: <bucket_region>
              s3ForcePathStyle: "true"
              s3Url: <bucket_url>
            credential:
              key: cloud
              name: cloud-credentials
            default: true
            objectStorage:
              bucket: <bucket_name>
              prefix: velero
            provider: aws
      configuration:
        nodeAgent:
          enable: true
          uploaderType: restic
        velero:
          client-burst: 500
          client-qps: 300
          defaultPlugins:
            - openshift
            - aws
            - kubevirt
    Copy to Clipboard Toggle word wrap

    where:

    client-burst
    Specifies the client-burst value. In this example, the client-burst field is set to 500.
    client-qps
    Specifies the client-qps value. In this example, the client-qps field is set to 300.
