# Kafka Flow

> Interactive Apache Kafka visualization for understanding how records move through producers, partitions, replicas, ISR, high watermarks, consumer groups, and share groups.

Kafka Flow is a deterministic teaching simulation. It is not a Kafka broker, benchmark, or capacity-planning tool.

## Primary resources

- [Interactive visualization](https://kafka-flow.com/): Run the simulation and change live Kafka controls.
- [Kafka concepts guide](https://kafka-flow.com/guide/): Crawlable HTML explanations for every concept shown in the visualization.
- [Complete machine-readable guide](https://kafka-flow.com/llms-full.txt): The same guide as concise Markdown.

## Scope

The simulation covers producer acknowledgments, max in-flight requests, partition routing, replication factor, ISR membership, minimum ISR, replica lag, high-watermark visibility, consumer-group ownership, share-group delivery, acquisition locks, and delivery counts.
