Apache Flink is an open source stream processing framework developed by the Apache Software Foundation. The core of Apache Flink is a distributed streaming dataflow engine written in Java and Scala. Flink executes arbitrary dataflow programs in a data-parallel and pipelined manner. Flink's pipelined runtime system enables the execution of bulk/batch and stream processing programs. Furthermore, Flink's runtime supports the execution of iterative algorithms natively.
Flink provides a high-throughput, low-latency streaming engine as well as support for event-time processing and state management. Flink applications are fault-tolerant in the event of machine failure and support exactly-once semantics. Programs can be written in Java, Scala,Python, and SQL and are automatically compiled and optimized into dataflow programs that are executed in a cluster or cloud environment.
Flink does not provide its own data storage system and provides data source and sink connectors to systems such as Amazon Kinesis, Apache Kafka, HDFS, Apache Cassandra, and ElasticSearch.
Apache Flink is developed under the Apache License 2.0 by the Apache Flink Community within the Apache Software Foundation. The project is driven by over 25 committers and over 275 contributors.
