Answer (1 of 3): [Disclaimer: I am an Apache Spark committer] TL;DR - Conceptually DAG model is a strict generalization of MapReduce model. There are usually two types of state that need to be stored, application state and processing engine operational states. Learn about messaging and stream processing technologies, and compare the pros and cons of the alternative solutions to Apache Kafka. Stream processing is for "infinite" or unbounded data sets that are processed in real-time. Flink consists of the following components for creating real-life applications as well as supporting machine learning and graph processing capabilities: Let us have a look at the basic principles on which Apache Flink is built: Apache Flink is an open-source platform for stream and batch data processing. An example of this is recording data from a temperature sensor to identify the risk of a fire. Incremental checkpointing, which is decoupling from the executor, is a new feature. It is designed to perform both batch processing (similar to MapReduce) and new workloads like streaming, interactive queries, and machine learning. Storm :Storm is the hadoop of Streaming world. Spark Streaming comes for free with Spark and it uses micro batching for streaming. Hence it is the next-gen tool for big data. Job Manager This is a management interface to track jobs, status, failure, etc. It promotes continuous streaming where event computations are triggered as soon as the event is received. Supports Stream joins, internally uses rocksDb for maintaining state. Excellent for small projects with dependable and well-defined criteria. These symbols have different meanings and are used for different purposes like oval or rounded shapes representing starting and endpoints of the process or task. Spark can achieve low latency with lower throughput, but increasing the throughput will also increase the latency. It has made numerous enhancements and improved the ease of use of Apache Flink. Flink supports batch and streaming analytics, in one system. I have shared detailed info on RocksDb in one of the previous posts. It has a more efficient and powerful algorithm to play with data. Native Streaming feels natural as every record is processed as soon as it arrives, allowing the framework to achieve the minimum latency . It is the future of big data processing. PyFlink has a simple architecture since it does provide an additional layer of Python API instead of implementing a separate Python engine.
