We've been working on IoT for around 3 years, and are recently targeting a use case of connected car that the scale is as follows:
* Concurrent connections over a million
* Throughput over 100 Gbps

We thought that Apache Kafka would be effective as a means of data collection function of IoT platform which satisfies these requirements. We built and tested the platform however we faced various issues below:
* Performance saturation of Kafka Producer NOT caused by depletion of computer resources
* Performance deterioration of Kafka Broker due to sudden disk IO
* Crash of Kafka Consumer due to sizing mistake between the Broker and Consumer

To solve the above issues and make full use of capabilities of the Kafka, it is necessary to clarify mechanism of the Kafka and its surroundings. This presentation will introduce pitfalls, solutions and best practices based on our experiences.
