Apache Cassandra Administrator Associate by Cristian Scutaru Pdf

Are you a system administrator or a DevOps looking for a valuable certification in the most popular NoSQL wide-column store? These two original practice tests will help you score big in your Apache Cassandra Administrator Associate certification exam.This book contains two high-quality practice tests similar to the proctored exam. Just like the actual exam, each exam practice test has 60 questions that you can try answer in 90 minutes or less. You may also consider a 70% passing score, just like for the real exam.DataStax, the largest provider of a commercial version for Apache Cassandra, is also the company that offers these Administrator and Developer certification exams. DataStax cut down the price for a certification exam to $145 US. But you can qualify for a free voucher and pay nothing, if you complete a learning path watching three of their courses online.This is not a brain dump, but the questions closely emulate those from the actual exam. All practice test questions are created by the author and do not repeat themselves. Each question has a detailed explanation and one or more references. The questions are divided in four categories: Architecture, Operations, Data Modeling, and CQL. While both the Administrator and Developer paths have some common recommended courses, the practice tests include several questions from my previously published Become a Certified Cassandra Developer: Practice Exams book.The exam has been updated in mid-2020, and we offer here the same level of difficulty as those latest exam questions. Most questions are single-select, with four possible choices. Few questions have multiple-choices. There are no True/False questions.What you don't have at the actual exam are the questions you missed, and the correct answers. We provide detailed explanations with link references for every question.The exam will test your administration skills for Apache Cassandra 3 and DataStax Enterprise 6. You should have some prior basic knowledge on the product. Go to their online documentation, and watch DataStax Academy's recommended videos for this certification exam, to know more.An interactive version of this book has been implemented on Udemy: Become a Certified Cassandra Administrator: Practice Exams.

Spark SQL 2.x Fundamentals and Cookbook by HadoopExam Learning Resources Pdf

Apache Spark is one of the fastest growing technology in BigData computing world. It support multiple programming languages like Java, Scala, Python and R. Hence, many existing and new framework started to integrate Spark platform as well in their platform e.g. Hadoop, Cassandra, EMR etc. While creating Spark certification material HadoopExam technical team found that there is no proper material and book is available for the Spark SQL (version 2.x) which covers the concepts as well as use of various features and found difficulty in creating the material. Therefore, they decided to create full length book for Spark SQL and outcome of that is this book. In this book technical team try to cover both fundamental concepts of Spark SQL engine and many exercises approx. 35+ so that most of the programming features can be covered. There are approximately 35 exercises and total 15 chapters which covers the programming aspects of SparkSQL. All the exercises given in this book are written using Scala. However, concepts remain same even if you are using different programming language. This book is good for following audiance - Data scientists - Spark Developer - Data Engineer - Data Analytics - Java/Python Developer - Scala Developer

Apache Spark Implementation on IBM z/OS by Lydia Parziale,Joe Bostian,Ravi Kumar,Ulrich Seelbach,Zhong Yu Ye,IBM Redbooks Pdf

The term big data refers to extremely large sets of data that are analyzed to reveal insights, such as patterns, trends, and associations. The algorithms that analyze this data to provide these insights must extract value from a wide range of data sources, including business data and live, streaming, social media data. However, the real value of these insights comes from their timeliness. Rapid delivery of insights enables anyone (not only data scientists) to make effective decisions, applying deep intelligence to every enterprise application. Apache Spark is an integrated analytics framework and runtime to accelerate and simplify algorithm development, depoyment, and realization of business insight from analytics. Apache Spark on IBM® z/OS® puts the open source engine, augmented with unique differentiated features, built specifically for data science, where big data resides. This IBM Redbooks® publication describes the installation and configuration of IBM z/OS Platform for Apache Spark for field teams and clients. Additionally, it includes examples of business analytics scenarios.

Practical Cassandra by Russell Bradberry,Eric Lubow Pdf

”Eric and Russell were early adopters of Cassandra at SimpleReach. In Practical Cassandra, you benefit from their experience in the trenches administering Cassandra, developing against it, and building one of the first CQL drivers. If you are deploying Cassandra soon, or you inherited a Cassandra cluster to tend, spend some time with the deployment, performance tuning, and maintenance chapters… If you are new to Cassandra, I highly recommend the chapters on data modeling and CQL.” –From the Foreword by Jonathon Ellis, Apache Cassandra Chair Build and Deploy Massively Scalable, Super-fast Data Management Applications with Apache Cassandra Practical Cassandra is the first hands-on developer’s guide to building Cassandra systems and applications that deliver breakthrough speed, scalability, reliability, and performance. Fully up to date, it reflects the latest versions of Cassandra–including Cassandra Query Language (CQL), which dramatically lowers the learning curve for Cassandra developers. Pioneering Cassandra developers and Datastax MVPs Russell Bradberry and Eric Lubow walk you through every step of building a real production application that can store enormous amounts of structured, semi-structured, and unstructured data. Drawing on their exceptional expertise, Bradberry and Lubow share practical insights into issues ranging from querying to deployment, management, maintenance, monitoring, and troubleshooting. The authors cover key issues, from architecture to migration, and guide you through crucial decisions about configuration and data modeling. They provide tested sample code, detailed explanations of how Cassandra works ”under the covers,” and new case studies from three cutting-edge users: Ooyala, Hailo, and eBay. Coverage includes Understanding Cassandra’s approach, architecture, key concepts, and primary use cases– and why it’s so blazingly fast Getting Cassandra up and running on single nodes and large clusters Applying the new design patterns, philosophies, and features that make Cassandra such a powerful data store Leveraging CQL to simplify your transition from SQL-based RDBMSes Deploying and provisioning through the cloud or on bare-metal hardware Choosing the right configuration options for each type of workload Tweaking Cassandra to get maximum performance from your hardware, OS, and JVM Mastering Cassandra’s essential tools for maintenance and monitoring Efficiently solving the most common problems with Cassandra deployment, operation, and application development
