Kafka producer (kafkaTemplate.send method ) takes longer time around 5 second to produce a message in topic when testing it with 90 hits per second constant load.
Few request (180 requests out of 175000) to Kafka template send method causes this issue.
I am using sprint-Kafka 2.8 version
I tried to change batch.size and linger.ms but no luck.
This application requires low latency
Any suggestion to fix this?
