Real-Time Exactly-Once Event Processing at Uber with Apache Flink, Kafka, and Pinot
Uber faced some challenges after introducing ads on UberEats. The events they generated had to be processed quickly, reliably and accurately. These requirements were fulfilled by a system based on Apache Flink, Kafka, and Pinot that can process streams of ad events in real-time with exactly-once semantics. An article describing its architecture was published recently in the Uber Engineering blog.

Why the Most Resilient Companies Want More Incidents
According to John Egan, the incident management process is meant to be a cycle of not just the response, but also the account of root cause and the updating of internal processes and practices across the industry. Lowering the barrier to reporting incidents, holding effective incident review meetings using blameless postmortems, and giving everyone access to postmortems is what he advises.
