In general, Kafka brokers are low in CPU, memory and I/Os. We do rely on
the broker server to cache all recent data in pagecache. The biggest
contraint is often the disk space, especially if you keep the default
retention time for 7 days. From this perspective, HDDs are better than SSDs
since the per MB cost is lower.
