expertReal System Design Problems
Design a Global Event Streaming Platform (like Kafka at LinkedIn scale) — trillions of messages per day.
The streaming-infrastructure-at-internet-scale problem: how a message queue processing trillions of messages a day is architected, how topics are partitioned and replicated across a global fleet of brokers, how consumer lag is monitored and managed, and how the platform survives the failure of an entire data center without losing messages or needing manual intervention.
