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. -
Nys Fair Events Mobile Application with Client-Side Caching
NYS FAIR EVENTS MOBILE APPLICATION WITH CLIENT-SIDE CACHING A Master’s Project Presented to Department of Computer and Information Sciences SUNY Polytechnic Institute Utica, New York In Partial Fulfilment of the requirements for the Master of Science Degree By Sumant Kanala (U00287895) December 2017 © SUMANT KANALA 2017 NYS Fair Events Mobile application with client-side caching Declaration I declare that this project is my own work and has not been submitted in any form for another degree or diploma at any university or other institute of tertiary education. Information derived from the published and unpublished work of others has been acknowledged in the text and a list of references is given. _________________ Sumant Kanala Abstract NYS Fair Events collects data about fair events which happen in New York state throughout the year, bundles them, displays the upcoming events and useful information about the event itself, the weather and forecast prediction, and a Google Maps to show the route to the event from the user’s location. The motivation for creating this project arose with understanding the growing market for mobile applications and by working for a startup for several months now in the field of web development. A trend has been established in which more users are switching towards mobile apps as their preferred information exchange tool than their traditional PCs and hence the development of better apps should be geared towards mobile phones and tablet PCs. The development of the app is mainly divided into two steps, the client and server side. For the client side I developed a Cordova-based mobile app which is cross-platform and can be compiled to work on Android and IOS based mobile devices. -
Technique: HTTP the Java Way
Technique: HTTP the Java way An article from Android in Practice EARLY ACCESS EDITION Charlie Collins, Michael D. Galpin, and Matthias Kaeppler MEAP Release: July 2010 Softbound print: Spring 2011 | 500 pages ISBN: 9781935182924 This article is taken from the book Android in Practice. The authors demonstrate how to send simple HTTP requests to a Web server using Java’s standard HTTP networking facilities. Tweet this button! (instructions here) Get 35% off any version of Android in Practice with the checkout code fcc35. Offer is only valid through www.manning.com. The standard Java class library already has a solution for HTTP messaging. An open-source implementation of these classes is bundled with Android’s class library, which is based on Apache Harmony. It’s simple and bare- bones in its structure and, while it supports features like proxy servers, cookies (to some degree), and SSL, the one thing that it lacks more than anything else is a class interface and component structure that doesn’t leave you bathed in tears. Still, more elaborate HTTP solutions are often wrappers around the standard Java interfaces and, if you don’t need all the abstraction provided, for example, by Apache HttpClient interfaces, the stock Java classes may not only be sufficient, they also perform much better thanks to a much slimmer, more low-level implementation. Problem You must perform simple networking tasks via HTTP (such as downloading a file) and you want to avoid the performance penalty imposed by the higher-level, much larger, and more complex Apache HttpClient implementation. Solution If you ever find yourself in this situation, you probably want to do HTTP conversations through a java.net.HttpURLConnection. -

Several approaches have been developed in this context proposing the storage and querying of RDF data in a distributed fashion, mainly using the MapReduce Programming Model and Hadoop-based ecosystems. New trends in Big Data technologies have also emerged (e.g., Apache Spark, Apache Flink); they use distributed in-memory processing and promise to deliver higher data processing performance. In this paper, we present a formal interpretation of some PACT transformations implemented in the Apache Flink DataSet API. We use this formalization to provide a mapping to translate a SPARQL query to a Flink program. The mapping was implemented in a prototype used to determine the correctness and performance of the solution.

XAMPP Web Development Stack
XAMPP Web Development Stack Overview @author R.L. Martinez, Ph.D. The steps below outline the processes for installing the XAMPP stack on a local machine. The XAMPP (pronounced Zamp) stack includes the following: Apache HTTP Server, MariaDB (essentially MySQL), Database Server, Perl, and the PHP Interpreter. The “X” in XAMPP is used to signify the cross-platform compatibility of the stack. The Apache HTTP Server and PHP are required to run phpMyAdmin which is a PHP application that is used for database administration tasks such as creating databases and tables, adding users, etc. Alternative to XAMPP If you have experience with MySQL Workbench, you may prefer to install MySQL Server and MySQL Workbench via the MySQL Installer. MySQL Workbench performs the same functions as phpMyAdmin. However, unlike phpMyAdmin which is a web-based application, MySQL Workbench is a locally installed application and therefore does not require an HTTP Server (e.g. Apache) to run. Installing XAMPP Many of the steps listed have several alternatives (such as changing MySQL passwords via a command line) and students are welcomed and encouraged to explore alternatives. 1. Download XAMPP from the URL below and place the installer (.exe) in the location where you want to install XAMPP. Placing the installer (.exe) in the same location as the intended installation is not required but preferred. http://www.apachefriends.org/download.html Page 1 of 17 XAMPP Web Development Stack 2. See the warning which recommends not installing to C:\Program Files (x86) which can be restricted by UAC (User Account Control). In the steps below XAMPP is installed to a USB flash drive for portability. -
