Analyzer java-kafka-req-latency

# Name

java-kafka-req-latency - Java Kafka Request Latency

This analyzer profiles Kafka request latency in Java applications using Kafka clients. It captures timing information for Kafka operations including produce and consume requests. The analyzer can optionally capture network packets for matched requests. It generates time-series charts that visualize Kafka request latency distribution over time, helping identify slow operations, network issues, and performance bottlenecks in Kafka-based Java applications.
