Section: Full talk Technical level: Intermediate
- Understanding life cycle of Kafka-request
- Understanding how a trivial (metrics addition) change caused a Kafka cluster to crumble under high load causing frontend user impact. (KAFKA-2664)
The talk is about a Kafka outage which caused frontend user impact. This is a very rare occation in Linkedin, where a backend messaging system outage causing front end impact. The presentation will touch base on Kafka request cycle, we would dissect a fetch request, will do profiling of verious API calls & also will talk about how we fixed the issue.
Good understanding of Kafka & Kafka ecosystem. We won’t be able to cover Kafka basics.
