What was the message throughput level at your previous workplace?

The message throughput in Kafka depends on the cluster configuration, hardware resources, and the nature of the load. At my previous job, we processed several tens of thousands of messages per second per topic.

For example, with configurations involving multiple brokers and partitions, as well as optimized producer and consumer settings, throughput can reach hundreds of megabytes per second.

It is important to consider that throughput depends on:

• message size
• number of partitions
• number of brokers
• producer settings (e.g., batch.size, linger.ms)
• consumer performance

In real projects, we monitored Kafka metrics and scaled the cluster as needed to support the required load.
