= Kafka topic name configuration
The default Kafka topic name that {registry} uses to store data is `kafkasql-journal`. This topic is created automatically by {registry}. However, you can override this behavior or the default topic name by setting the appropriate environment variable or Java system property:

.Kafka topic name configuration
[%header,cols="3,3,2"]

| `kafkasql-journal`
| `REGISTRY_KAFKASQL_TOPIC_AUTO_CREATE`
| `registry.kafkasql.topic.auto-create`
| `true`
