Apache Kafka has become a cornerstone in modern distributed systems, particularly for real-time data processing applications. However, as data volumes and processing demand increase, minimizing latency becomes crucial for maintaining system performance and responsiveness. This research article explores various techniques for reducing latency in Kafka-based systems, focusing on both producer-side and consumer-side optimizations, as well as broker configurations. We examine strategies such as batching, compression, partitioning schemes, and consumer group designs, and their impact on overall system latency. Our findings suggest that a combination of these techniques, when properly implemented, can significantly reduce end-to-end latency in Kafka- based real-time data processing applications.
