Confluent

This page describes connecting Lenses to Confluent schema registries.

Only one Schema Registry connection is allowed.

Name must be schema-registry.

See JSON schema for support.

Environment variables are supported; escape the dollar sign

sslKeystorePassword:
  value: "\${ENV_VAR_NAME}"

Simple configuration, with JMX metrics

The URLs (nodes) should always have a scheme defined (http:// or https://).

confluentSchemaRegistry:
  - name: schema-registry
    tags: ["tag1"]
    version: 1      
    configuration:
      schemaRegistryUrls:
        value:
          - http://my-sr.host1:8081
          - http://my-sr.host2:8081
      ## all metrics properties are optional
      metricsPort: 
        value: 9581
      metricsType: 
        value: JMX
      metricsSsl: 
        value: false

Basic authentication

For Basic Authentication, define username and password properties.

confluentSchemaRegistry:
- name: schema-registry
  tags: ["tag1"]
  version: 1    
  configuration:
    schemaRegistryUrls:
      value:
        - http://my-sr.host1:8081
        - http://my-sr.host2:8081
    username: 
      value: my-username
    password: 
      value: my-password

TLS with custom truststore

A custom truststore is needed when the Schema Registry is served over TLS (encryption-in-transit) and the Registry’s certificate is not signed by a trusted CA.

confluentSchemaRegistry:
  - name: schema-registry
    tags: ["tag1"]
    version: 1      
    configuration:
      schemaRegistryUrls:
        value:
          - https://my-sr.host1:8081
          - https://my-sr.host2:8081
      sslTruststore:
        file: schema-truststore.jks
      sslTruststorePassword: 
        value: myPassword

TLS with client authentication

A custom truststore might be necessary too (see above).

confluentSchemaRegistry:
  - name: schema-registry
    tags: ["tag1"]
    version: 1      
    configuration:
      schemaRegistryUrls:
        value:
          - https://my-sr.host1:8081
          - https://my-sr.host2:8081
      sslKeystore:
        file: schema-keystore.jks
      sslKeystorePassword: 
        value: myPassword

Hard or soft delete

By default, Lenses will use hard delete for Schema Registry. To use soft delete, add the following property:

confluentSchemaRegistry:
  - name: schema-registry
    tags: ["tag1"]
    version: 1      
    configuration:
      schemaRegistryUrls:
        value:
          - http://my-sr.host1:8081
          - http://my-sr.host2:8081
      hardDelete:
        value: true
