KafkaConsumer Node allows multiple consumers in a CGID under "Additional Instance" setting

We would like to scale our ACE12 flow performance based on KafkaConsumer input node and its Additional Instance setting.


Let's say our Kafka topic partition is 100 partitions. Our other Java program can easily scale up from single consumer/thread to 40 consumers/threads within a CGID by tuning up the ConsumerCount setting. The performance scaled up very well in that Java custom coding. It is very difficult and tedious to deploy 40 duplicated ACE12 flows to achieve that 40 consumers for performance improvement.


Currently, the behavior of "Additional Instance" maybe multi-threaded, but still 1 Kafka consumer within a CGID. It didn't take advantage of multiple Kafka consumers and consumer group features for concurrency performance as well as partition-level message affinity. This current ACE12 Additional Instance behavior also screw up the partition level message affinity. If "Additional Instance" means "Additional Thread and Additional Kafka Consumer", performance and partition level message affinity will be perfect.


Please kindly consider this feature which can greatly enhance the performance of ACE12 flow with Kafka.

    Thank you for taking the time to raise this idea, and apologies for the length of time before replying. We very much support the enhancement suggestion, but note that in order to implement this change within ACE would require a significant change in the way that the Kafka node is currently architected. This architectural change is currently being considered in combination with some other Kafka externals suggestions and it is likely that we will scoop together multiple of these externals and address them at the same time. For now, the status of this item is updated to Future Consideration.
