Hi, I have been playing around with different kafka configurations at producer, broker and consumer side.
But could not figure out a way to get predictable low latency below 5 to 10 ms. *Use Case:* - Application has 100-200 producers, each producer is producing messages at different rates. Ex. 1 msg/sec, 10 msgs/sec, 100msgs/sec (100msg/sec is the max limit) - Each producer is producing messages on unique topic on a same partition so that ordering is maintained which is business requirement. - Every producer has corresponding consumers. Some producers might have 1-10 consumers. As I look at the above use case, I do not see I would be getting benefits of batching which kafka is heavily depends on for getting maximum throughput. >From whole system I expect max throughput of around 40 - 50k but we would like to achieve latency below 5-10 ms. Is it possible with kafka to get this numbers of latency and throughput? Note: I tried different configs focussing on latency part, but could not get latency below 150ms, for example kafka-clients { linger.ms=0 acks=0 batch.size=1 } akka.kafka.consumer { poll-interval = 0 poll-timeout = 0 } Thanks, Pritam.
