Apache Flink™: Stream and Batch Processing in a Single Engine
Apache Flink™: Stream and Batch Processing in a Single Engine Paris Carboney Stephan Ewenz Seif Haridiy Asterios Katsifodimos* Volker Markl* Kostas Tzoumasz yKTH & SICS Sweden zdata Artisans *TU Berlin & DFKI parisc,[email protected] fi[email protected] fi[email protected] Abstract Apache Flink1 is an open-source system for processing streaming and batch data. Flink is built on the philosophy that many classes of data processing applications, including real-time analytics, continu- ous data pipelines, historic data processing (batch), and iterative algorithms (machine learning, graph analysis) can be expressed and executed as pipelined fault-tolerant dataflows. In this paper, we present Flink’s architecture and expand on how a (seemingly diverse) set of use cases can be unified under a single execution model. 1 Introduction Data-stream processing (e.g., as exemplified by complex event processing systems) and static (batch) data pro- cessing (e.g., as exemplified by MPP databases and Hadoop) were traditionally considered as two very different types of applications. They were programmed using different programming models and APIs, and were exe- cuted by different systems (e.g., dedicated streaming systems such as Apache Storm, IBM Infosphere Streams, Microsoft StreamInsight, or Streambase versus relational databases or execution engines for Hadoop, including Apache Spark and Apache Drill). Traditionally, batch data analysis made up for the lion’s share of the use cases, data sizes, and market, while streaming data analysis mostly served specialized applications. It is becoming more and more apparent, however, that a huge number of today’s large-scale data processing use cases handle data that is, in reality, produced continuously over time. -

Apache Storm Tutorial
Apache Storm Apache Storm About the Tutorial Storm was originally created by Nathan Marz and team at BackType. BackType is a social analytics company. Later, Storm was acquired and open-sourced by Twitter. In a short time, Apache Storm became a standard for distributed real-time processing system that allows you to process large amount of data, similar to Hadoop. Apache Storm is written in Java and Clojure. It is continuing to be a leader in real-time analytics. This tutorial will explore the principles of Apache Storm, distributed messaging, installation, creating Storm topologies and deploy them to a Storm cluster, workflow of Trident, real-time applications and finally concludes with some useful examples. Audience This tutorial has been prepared for professionals aspiring to make a career in Big Data Analytics using Apache Storm framework. This tutorial will give you enough understanding on creating and deploying a Storm cluster in a distributed environment. Prerequisites Before proceeding with this tutorial, you must have a good understanding of Core Java and any of the Linux flavors. Copyright & Disclaimer © Copyright 2014 by Tutorials Point (I) Pvt.

The technology currently Besöksadress: existing provides the tools to process these data and gain more meaningful Ångströmlaboratoriet Lägerhyddsvägen 1 information out of it. This thesis has two parts: theoretical and practical. The Hus 4, Plan 0 theoretical part investigates what tools are there that are suitable for stream data flow processing and analysis. In doing so, it starts with studying one of the main Postadress: streaming data source that produce large volumes of data: Internet of Things. In this, Box 536 751 21 Uppsala the technologies behind it, common use cases, challenges, and solutions are studied. Then it is followed by overview of selected tools namely Apache NiFi, Apache Spark Telefon: Streaming and Apache Storm studying their key features, main components, and 018 – 471 30 03 architecture. After the tools are studied, 5 parameters are selected to review how Telefax: each tool handles these parameters. This can be useful for considering choosing 018 – 471 30 00 certain tool given the parameters and the use case at hand. The second part of the thesis involves Twitter data analysis which is done using Apache NiFi, one of the tools Hemsida: studied. The purpose is to show how NiFi can be used for processing data starting http://www.teknat.uu.se/student from ingestion to finally sending it to storage systems. -

Defining this is not worth the time Ever heard of The Blind Men and The Elephant? If you still need one, see NIST definition next slide The idea is to consume X as-a-service, where X can be Computing, storage, analytics, etc. X can come from 3 categories Infrastructure-as-a-S, Platform-as-a-Service, Software-as-a-Service Classic Cloud Computing Computing IaaS PaaS SaaS My washer Rent a washer or two or three I tell, Put my clothes in and My bleach My bleach comforter dry clean they magically appear I wash I wash shirts regular clean clean the next day 6/10/2016 2 The Three Categories • Software-as-a-Service Provides web-enabled software Ex: Google Gmail, Docs, etc • Platform-as-a-Service Provides scalable computing environments and runtimes for users to develop large computational and big data applications Ex: Hadoop MapReduce • Infrastructure-as-a-Service Provide virtualized computing and storage resources in a dynamic, on-demand fashion. Ex: Amazon Elastic Compute Cloud 6/10/2016 3 The NIST Definition of Cloud Computing? • “Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.” On-demand self-service, broad network access, resource pooling, rapid elasticity, measured service, http://nvlpubs.nist.gov/nistpubs/Legacy/SP/nistspecialpublication800-145.pdf • However, formal definitions may not be very useful. -

Procedure 1. Click the Ambari "Services" tab. 2. In the Ambari "Actions" menu, select "Add Service." This starts the Add Service Wizard, displaying the Choose Services screen. Some of the services are enabled by default. 3. Scroll down through the alphabetic list of components on the Choose Services page, select "Storm", and click "Next" to continue: 3 Apache Kafka Installing Apache Storm 4 Apache Kafka Installing Apache Storm 4. On the Assign Masters page, review node assignments for Storm components. If you want to run Storm with high availability of nimbus nodes, select more than one nimbus node; the Nimbus daemon automatically starts in HA mode if you select more than one nimbus node. Modify additional node assignments if desired, and click "Next". 5. On the Assign Slaves and Clients page, choose the nodes that you want to run Storm supervisors and clients: Storm supervisors are nodes from which the actual worker processes launch to execute spout and bolt tasks. Storm clients are nodes from which you can run Storm commands (jar, list, and so on). 6. Click Next to continue. 7. Ambari displays the Customize Services page, which lists a series of services: 5 Apache Kafka Installing Apache Storm For your initial configuration you should use the default values set by Ambari.
