Apache Spark Quick Start Guide. Quickly learn the art of writing efficient big data applications with Apache Spark

Shrey Mehrotra, Akash Grade

Apache Spark is a ?exible framework that allows processing of batch and real-time data. Its unified engine has made it quite popular for big data use cases. This book will help you to get started with Apache Spark 2.0 and write big data applications for a variety of use cases.It will also introduce you to Apache Spark – one of the most popular Big Data processing frameworks. Although this book is intended to help you get started with Apache Spark, but it also focuses on explaining the core concepts. This practical guide provides a quick start to the Spark 2.0 architecture and its components. It teaches you how to set up Spark on your local machine. As we move ahead, you will be introduced to resilient distributed datasets (RDDs) and DataFrame APIs, and their corresponding transformations and actions. Then, we move on to the life cycle of a Spark application and learn about the techniques used to debug slow-running applications. You will also go through Spark’s built-in modules for SQL, streaming, machine learning, and graph analysis.Finally, the book will lay out the best practices and optimization techniques that are key for writing efficient Spark applications. By the end of this book, you will have a sound fundamental understanding of the Apache Spark framework and you will be able to write and optimize Spark applications.

Applying and Extending Oracle Spatial. This guide takes you straight into the attributes of Oracle Spatial and teaches you to extend, apply, and combine them with other Oracle and open source technologies. A vital manual for solving everyday problems

Siva Ravada, Simon Greener

Spatial applications should be developed in the same way that users develop other database applications: by starting with an integrated data model in which the SDO_GEOMETRY objects are just another attribute describing entities and by using as many of the database features as possible for managing the data. If a task can be done using a database feature like replication, then it should be done using the standard replication technology instead of inventing a new procedure for replicating spatial data. Sometimes solving a business problem using a PL/SQL function can be more powerful, accessible, and easier to use than trying to use external software. Because Oracle Spatial's offerings are standards compliant, this book shows you how Oracle Spatial technology can be used to build cross-vendor database solutions. Applying and Extending Oracle Spatial shows you the clever things that can be done not just with Oracle Spatial on its own, but in combination with other database technologies. This is a great resource book that will convince you to purchase other Oracle technology books on non-spatial specialist technologies because you will finally see that spatial is not special: it is a small, fun, and clever part of a much larger whole.

Archiwizacja i odzyskiwanie danych

W. Curtis Preston

Optymalizacja procesu archiwizacji dla administratorów i nie tylko Jak archiwizować i odtwarzać system oraz dane? Jak wybrać optymalną metodę archiwizacji? Jak ograniczyć koszty związane z procesem archiwizacji? Wdrożenie systemu archiwizacji jest podstawową czynnością, jaką administrator powinien wykonać. Cel tej procedury jest oczywisty, tak jak cena, jaką przyjdzie zapłacić za brak takiego systemu. Utrata danych lub krach systemu wcale nie muszą oznaczać dla firmy długiego postoju i narażać jej na wielkie straty; wtedy to właśnie wysiłek, jaki włożył administrator w system archiwizacji, jest doceniany przez pracodawców i współpracowników. Jakie urządzenia i narzędzia należy zastosować, aby ten proces był sprawny i szybki, a jednocześnie zmieścił się w wyznaczonym do tego celu budżecie? Opisane oprogramowanie i rady udzielone przez autora tej książki pomogą Ci dokonać właściwego wyboru. "Archiwizacja i odzyskiwanie danych" to przewodnik po darmowych narzędziach do archiwizacji i odzyskiwania danych, przeznaczony głównie dla administratorów. W. Curtis Preston, specjalista w dziedzinie ochrony danych, zwrócił uwagę, że środki przeznaczone na system archiwizacji są często zbyt małe, by zapewnić mu wysoką skuteczność. Przyglądając się bliżej bezpłatnym narzędziom, odkrył ich duże możliwości; swoje spostrzeżenia i uwagi na ich temat zapisał w tej książce. Prędzej czy później każdy administrator staje przed koniecznością odbudowania systemu lub odzyskania danych i właśnie lektura tej książki sprawi, że będzie na to przygotowany! Narzędzia do archiwizacji i odtwarzania danych Przegląd programów komercyjnych i darmowych Urządzenia archiwizujące Przywracanie komputera od podstaw z wybranym systemem operacyjnym Archiwizacja i odtwarzanie baz danych Sposoby zabezpieczania archiwum i magazynów danych Wykorzystanie wirtualnych maszyn w procesie archiwizacji Poszerz swoją wiedzę i archiwizuj dane we właściwy, a także sprawdzony sposób!
