In this Apache Flink Tutorial, we will discuss the introduction to Apache Flink, What is Flink, Why and where to use Flink. Moreover, this Apache Flink tutorial will\u00a0answer the question of why Apache\u00a0Flink\u00a0is called 4G of Big Data? The tutorial also briefs about Flink APIs and features.<\/p>\n

So, let’s start Apache Flink tutorial.<\/p>\n

Introduction to Apache Flink<\/h3>\n

Apache Flink is an open source platform which is a streaming data flow engine that provides communication, fault-tolerance, and data-distribution for distributed computations over data streams. Flink is a top-level project of Apache. It is a scalable data analytics <\/strong>framework that is fully compatible with Hadoop<\/strong>. Flink can execute both stream processing and batch processing easily.<\/p>\n

Apache Flink was started under the project called The Stratosphere. In 2008 Volker Markl formed the idea for Stratosphere and attracted other co-principal Investigators from HU Berlin, TU Berlin, and the Hasso Plattner Institute Potsdam. They jointly worked on a vision and had already put the great efforts on open source deployment and systems building.<\/p>\n

\n

Later on, several decisive steps had been so that the project can be popular in commercial, research and open source community. A commercial entity named this project as Stratosphere. After applying for Apache incubation in April 2014 Flink name was finalized. Flink is a German word which means swift or agile. To learn more about Flink introduction.<\/p>\n

Why Flink?<\/h3>\n

The key vision for Apache Flink is to overcome and reduces the complexity that has been faced by other distributed data-driven engines. This achieved by integrating query optimization, concepts from database systems and efficient parallel in-memory and out-of-core algorithms, with the MapReduce<\/strong> framework. So, Apache Flink is mainly based on the streaming model, Apache Flink iterates data by using streaming architecture. Now, the concept of an iterative algorithm bound into Flink query optimizer. So, Apache Flink\u2019s pipelined architecture allows processing the streaming data faster with lower latency than micro-batch architectures (Spark<\/strong>).<\/p>\n

Apache Flink Tutorial – API\u2019s<\/h3>\n

Apache Flink provides APIs for creating several applications which use flink engine-<\/p>\n

\"Apache<\/a><\/p>\n

i. DataStream APIs<\/h4>\n

Basically, it is a regular program in Apache Flink that implements the transformation on data streams For example- filtering, aggregating, update state etc. Results that return through sink which we can generate through write data on files or in a command line terminal.<\/p>\n

ii. DataSet APIs<\/h4>\n

It is a regular program in Apache Flink that implements the transformation on data sets For example joining, grouping, mapping, filtering etc. We use this API for batch processing of data, the data which is already available in the repository.<\/p>\n

iii. Table APIs<\/h4>\n

This API in Flink used for handling relational operations. So, it is a SQL<\/strong>-like expression language used for relational stream and batch processing which we can also integrate into Datastream APIs and Dataset APIs.<\/p>\n

Features of Apache Flink<\/h3>\n

Let us now see the various features of Apache Flink that makes it so useful:<\/p>\n

i. Low latency and High Performance<\/h4>\n

Apache Flink provides high performance and Low latency without any heavy configuration. Its pipelined architecture provides the high throughput rate. It processes the data at lightening fast speed, it is also called as 4G of Big Data.<\/p>\n

ii. Fault Tolerance<\/h4>\n

The fault tolerance feature provided by Apache Flink is based on Chandy-Lamport distributed snapshots, this mechanism provides the strong consistency guarantees.<\/p>\n

iii. Memory Management<\/h4>\n

So, the memory management in Apache Flink provides control on how much memory we use in certain runtime operations.<\/p>\n

iv. Iterations<\/h4>\n

Apache Flink provides the dedicated support for iterative algorithms (machine learning, graph processing)<\/p>\n

v. Integration<\/h4>\n

We can easily integrate Apache Flink with other open source data processing ecosystem. It can be integrated with Hadoop, streams data from Kafka, It can be run on YARN.<\/p>\n

vi. Scalability<\/h4>\n

Conclusion – Apache Flink Tutorial<\/h3>\n

So, in this Apache Flink tutorial, we discussed the meaning of Flink. Moreover, we looked at the need for Flink. Also, we saw Flink features and API for Flink. Still, if you have any doubt in Apache Flink Tutorial, ask in the comment tabs.<\/p>\n
