Apache Flink

Apache Flink is a distributed processing engine designed for stateful computations over unbounded and bounded data streams at any scale.

Flink excels at high-throughput, low-latency stream processing by treating everything as a stream. It manages local state across a cluster with exactly-once consistency guarantees (crucial for financial ledgers or inventory tracking). The engine handles late-arriving data using sophisticated watermarking and supports diverse deployment modes including Kubernetes and YARN. Whether you are running sub-second fraud detection or massive batch ETL jobs, Flink provides the APIs (Java, Python, SQL) to process millions of events per second with sub-millisecond latency.
