How to analyze the cost of Kafka?
The article discusses the common cost inefficiencies associated with using Kafka. It highlights five key patterns that lead to overspending, including partition overprovisioning and unnecessary cluster sprawl. Recommendations for optimizing costs include setting sensible defaults and regularly reviewing Kafka environments.
- ▪Most Kafka teams are overpaying by 25 to 40 percent due to inefficient usage patterns.
- ▪Common issues include partition overprovisioning, long retention periods for unused topics, and the existence of zombie topics.
- ▪Optimizing costs can involve setting lower defaults for partitions and retention, as well as consolidating Kafka clusters.
