Apache Flink

Apache Flink is a wildly explosive, deeply specialized open-source disruptor that mathematically attacked the "Stateful Processing" bottleneck of older streaming engines. While older systems process data in micro-batches, Flink engineered a terrifyingly precise, true event-at-a-time streaming engine. It is the absolute weapon of choice for elite algorithmic trading firms who mathematically demand to calculate highly complex, stateful financial risk models on live data with absolute sub-millisecond physical latency.
