Application Settings

Application Settings describes application settings for CDR Kafka router. For descriptions of all the available parameters (including these), see the discussion about configuring CDR Kafka router.

Table 1. Application Settings
Property	Description
Global Settings
router.port	The container port to use for metrics and ready check. The default value is 8282.
router.topic	The inbound topic. The default value is `sba-cdr`. This property is overridden by Helm properties, where those are present.
router.metrics.enabled	When set to `true`, the service exports Prometheus metrics. The default value is `true`.
router.metrics.endpoint	The service address for metrics. The default value is `/metrics`.
router.shutdownSeconds	Time in seconds before shutting down the streaming applications. The default value is 5.
router.connectionBackOffSeconds	Time in seconds to pause before re-trying to connect to Kafka on start-up, in seconds. The default value is 10.
router.configuration	A map of configuration options used to override Kafka Streams configuration defaults, for example `bootstrap.servers`: `router.configuration.bootstrap.servers=kafka:29092` Configuration applied with `router.configuration` applies to both applications. A value for `bootstrap.server` must be provided. The value of `bootstrap.server` is overridden by the Helm chart values, where those are present.
Enrichment and Routing Settings
router.consumerId	Consumer group ID for the routing application. This is only used if not specified with `routing.configuration.application.id`. The default value is `mtx-sba-events-router-1`.
router.tags	The list of `item` elements to test for and apply.
router.routing.noMatch	The routing topic when no match is made.
router.routing.routes	The routing configuration.
Transformation Settings
router.transform.enabled	When set to `true`, the transform function is created. The default value is `false`. This property is overridden by Helm properties, where those are present.
router.transform.inbound	The inbound topic for transformation. This property is overridden by Helm properties, where those are present.
router.transform.outbound	The outbound topic for transformation. This property is overridden by Helm properties, where those are present.
router.transform.consumerId	The consumer group ID for transformer. The default value is `mtx-sba-events-transformer-1`.

The router.configuration Kafka options are used for both applications. If application.id is supplied, it is used instead of router.consumerId for the routing application. The property is overwritten for the transform application if it is enabled, using router.transform.consumerId.

The following is a minimal configuration using the transformation function only:

router:
    configuration:
        bootstrap.servers: kafka:9092
    transform:
        enabled: true
        inbound: inbound.topic
        outbound: outbound.topic
