Many client application and micro-services which use Advanced Queuing for messaging have better performance if they use JSON data type to handle JavaScript Object Notation (JSON) messages. constants. Extending Oracle Streaming with Kafka Compatibility by Somnath Lahiri. But let us first take a step back and see its connection with Advanced Queuing. It makes it easy to receive (by periodically fetching) all events on a Kafka topic of interest. If no partitions have been added to the topic, then the procedure will terminate rows. </dependency> Producer application.properties Replace the bootstrap servers with the IP's of your Kafka brokers separated by commas if there are multiple nodes.
