Kafka - WunderGraph

Definitions

The providerId argument, including the default value “default”, must correspond to an equivalent property in events.providers.kafka entry of the router config.yml.

Kafka topic arguments support argument templates such as employeeUpdated.{{ args.employeeID }}. If you use templates, create the rendered Kafka topics in your broker ahead of time because the Router does not create topics automatically.

    success: Boolean!
}

Argument name	Type	Value
