Apache Flink was developed by Apache Software Foundation, and is one of the latest entries on the list of open-source frameworks focused on big data analytics. Apache Flink had its first stable API version published in March 2016, and was built for the in-memory processing of batch data, just like Spark.

This model comes in handy when repeated passes need to be made on the same data. This makes it an ideal candidate for machine learning and other use cases that require adaptive learning, self-learning networks, and so on.
