Apache Flink

Apache Flink is an open-source framework and distributed processing engine for stateful computations over unbounded and bounded data streams. It is designed to run in all common cluster environments and to perform computations at in-memory speed and at any scale. Flink exposes a REST API on the JobManager Dispatcher that allows external systems to query cluster status, submit and manage jobs, trigger savepoints and checkpoints, upload and run JARs, and inspect metrics, accumulators, and exception histories. The same REST endpoints power the Flink Web UI.

Apache Flink publishes 7 APIs on the APIs.io network, including Checkpoints API, Cluster API, Datasets API, and 4 more. Tagged areas include Big Data, Distributed Computing, Real-Time Analytics, Stream Processing, and Workflows.

Apache Flink’s developer surface includes documentation, engineering blog, and 10 more developer resources.
