### What is the best practice for converting a batch dataset to a stream for exporting to Kafka?

The best practice is to create a streaming pipeline in Pipeline Builder, using a batch dataset as the input and configuring the output as a stream. This stream can then be exported to Kafka, following the normal [Kafka streaming export documentation](../../available-connectors/kafka/index.md#export-data-to-kafka).
