Apache Flink is an open source platform for scalable batch and stream data processing.

Apache Flink is …

• The core of Apache Flink is a distributed streaming dataflow engine.• Executing dataflows in

parallel on clusters• Providing a reliable

foundation for various workloads

• DataSet and DataStream programming abstractions are the foundation for user programs and higher layers

One engine for many use cases
