About:
Khaos is a specialized command-line tool designed to generate realistic and controllable Kafka traffic for testing and development environments. It enables engineers to simulate various data patterns, message volumes, and potential failure scenarios to validate system resilience. This makes it an essential utility for chaos engineering and performance tuning within Kafka-based architectures.

Key Features:

Simulates realistic Kafka message streams with customizable patterns
Supports chaos engineering by injecting latency and errors
Lightweight CLI for easy integration into development workflows
Helps validate consumer and producer performance under load

Use Cases:

Testing Kafka consumer logic against unpredictable data streams
Validating cluster resilience by simulating message backpressure
Performance benchmarking of Kafka producers and consumers
Developing and debugging stream processing applications locally

Alternatives:

kafka-producer-perf-test – Khaos offers more flexible data patterns and chaos features compared to the standard Kafka benchmarking tool.
ksqlDB – ksqlDB is for stream processing, whereas Khaos is focused purely on traffic generation and simulation.
