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 7 more developer resources.

Where this information came from

This is an independent, third-party profile of Apache Flink, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
