Stateful Computations over Data Streams

Apache Flink is a framework and distributed processing engine for stateful computations over unbounded and bounded data streams. Flink has been designed to run in all common cluster environments, perform computations at in-memory speed and at any scale.

Use Cases
Event Driven Applications

An event-driven application is a stateful application that ingests events from one or more event streams and reacts to incoming events by triggering computations, state updates, or external actions.

Stream & Batch Analytics

Analytical jobs extract information and insight from raw data. Apache Flink supports traditional batch queries on bounded data sets and real-time, continuous queries from unbounded, live data streams.

Data Pipelines & ETL

Extract-transform-load (ETL) is a common approach to convert and move data between storage systems.
