Kafka Quotas
KafkaClientQuota resources are used to define the quota limits to be applied on Kafka consumers and producers.
A KafkaClientQuota resource can be used to apply limit to consumers and/or producers identified by a client-id or a
user principal.
KafkaClientQuota
Specification
Here is the resource definition file for defining a KafkaClientQuota.
apiVersion: "kafka.jikkou.io/v1beta2" # The api version (required)
kind: "KafkaClientQuota"              # The resource kind (required)
metadata: # (optional)
  labels: { }
  annotations: { }
spec:
  type: <The quota type> # (required)       
  entity:
    clientId: <The id of the client>    # (required depending on the quota type).
    user: <The principal of the user>   # (required depending on the quota type).
  configs:
    requestPercentage: <The quota in percentage (%) of total requests>      # (optional)
    producerByteRate: <The quota in bytes for restricting data production>  # (optional)
    consumerByteRate: <The quota in bytes for restricting data consumption> # (optional)
Quota Types
The list below describes the supported quota types:
USERS_DEFAULT: Set default quotas for all users.USER: Set quotas for a specific user principal.USER_CLIENT: Set quotas for a specific user principal and a specific client-id.USER_ALL_CLIENTS: Set default quotas for a specific user and all clients.CLIENT: Set default quotas for a specific client.CLIENTS_DEFAULT: Set default quotas for all clients.
Example
Here is a simple example that shows how to define a single YAML file containing two quota definitions using
the KafkaClientQuota resource type.
file: kafka-quotas.yaml
---
apiVersion: 'kafka.jikkou.io/v1beta2'
kind: 'KafkaClientQuota'
metadata:
  labels: { }
  annotations: { }
spec:
  type: 'CLIENT'
  entity:
    clientId: 'my-client'
  configs:
    requestPercentage: 10
    producerByteRate: 1024
    consumerByteRate: 1024
---
apiVersion: 'kafka.jikkou.io/v1beta2'
kind: 'KafkaClientQuota'
metadata:
  labels: { }
  annotations: { }
spec:
  type: 'USER'
  entity:
    user: 'my-user'
  configs:
    requestPercentage: 10
    producerByteRate: 1024
    consumerByteRate: 1024
KafkaClientQuotaList
If you need to define multiple topics (e.g. using a template), it may be easier to use a KafkaClientQuotaList
resource.
Specification
Here the resource definition file for defining a KafkaTopicList.
apiVersion: "kafka.jikkou.io/v1beta2"  # The api version (required)
kind: "KafkaClientQuotaList"           # The resource kind (required)
metadata: # (optional)
  name: <The name of the topic>
  labels: { }
  annotations: { }
items: [ ]                              # An array of KafkaClientQuota
Example
Here is a simple example that shows how to define a single YAML file containing two KafkaClientQuota definition using
the KafkaClientQuotaList resource type.
apiVersion: 'kafka.jikkou.io/v1beta2'
kind: 'KafkaClientQuotaList'
metadata:
  labels: { }
  annotations: { }
items:
  - spec:
    type: 'CLIENT'
    entity:
      clientId: 'my-client'
    configs:
      requestPercentage: 10
      producerByteRate: 1024
      consumerByteRate: 1024
  - spec:
      type: 'USER'
      entity:
        user: 'my-user'
      configs:
        requestPercentage: 10
        producerByteRate: 1024
        consumerByteRate: 1024
