Apache Kafka Practice

Disk performance significantly influences the latency experienced by producers in Kafka. When producers send messages to Kafka, these messages are written to disk, and the speed at which this writing occurs directly affects how quickly the producers can send their next messages. If the disk's write speed is slow, it creates a bottleneck, causing producers to wait longer before they can send more data. This leads to increased latency since the time taken to acknowledge the write operation back to the producer will be longer. Conversely, if the disk performance is high, with faster write speeds, producers can efficiently send messages with minimal delays, thereby improving overall performance. This relationship between disk speed and producer latency emphasizes the importance of good disk performance in maintaining the responsiveness and effectiveness of Kafka as a messaging system. Additionally, disk performance is also essential for consumer operations, but the primary concern here is how it impacts producers and their ability to send messages rapidly, which is why this choice is particularly accurate.
