Apache Flink
Stateful Computations over Data Streams
- Also known as
- apache-flink
What is Apache Flink?
A framework and distributed processing engine for stateful computations over unbounded and bounded data streams, designed to run in all common cluster environments with in-memory speed and at any scale.

The Vioscale score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Apache Flink, not the verdict.
