What is Flink - Introduction to Flink | Apache Flink Tutorial

Apache Flink is the successor to Hadoop and Spark. Flink is the next generation engine for Stream processing. If Hadoop is 2G, Spark is 3G then Apache Flink is the 4G in Big data stream processing frameworks.
Actually Spark was not a true Stream processing framework, it was just a makeshift to do it but Apache Flink is a TRUE Streaming engine with added capacity to perform Batch, Graph, Table processing and also to run Machine Learning algorithms.
Apache Flink is the latest Big data technology and is rapidly gaining momentum in the market. It is assumed that same like Spark replaced Hadoop, Flink can also replace Spark in the coming near future.
