Apache Flink® is an open source stream processing framework that unifies real-time event-driven applications and real-time analytics. -Performance State modifications and lookups are local to an Apache Flink application, and backups are managed without any disruption in data processing. -Scalability Apache Flink stream processing applications manage their own data and state, reducing the need for expensive shared databases. Resources for compute and state can be scaled jointly. -Exactly-once Semantics Global backup snapshots for fault tolerance ensure a consistent view of an Apache Flink application, guaranteeing fault tolerance and exactly-once application semantics.
