This includes: Application Developers: Building high-performance, scalable applications. Data Architects: Designing robust and efficient data solutions. Database Designers: Crafting optimal schema for Cassandra. Database Administrators: Managing and maintaining Cassandra deployments. Candidates are encouraged to follow a structured Learning Path, composed of recommended courses curated by Curriculum Engineers. A basic familiarity with programming concepts, the Unix/Linux command line, and networking and storage principles is assumed. What Topics Are Covered on the Exam? A Comprehensive Overview The certification exam rigorously assesses your understanding of Apache Cassandra's core concepts and practical applications. Key areas of focus include: Core Topics: Cassandra Architecture: Deep dive into the ring topology, nodes, replication strategies, consistency models, and how Cassandra achieves unparalleled scalability, availability, performance, fast response times, and low latency. Storing & Retrieving Data: Mastery of Cassandra Query Language (CQL) operations, including INSERT, UPDATE, DELETE, and SELECT statements. Understanding tools and techniques for efficient bulk data loading and unloading. Developer Exam Topics: Data Modeling: Comprehensive knowledge of conceptual, logical, and physical data models. This includes defining schema elements such as keyspaces, tables, columns, partition keys, clustering columns, user-defined types (UDTs), collections, secondary indexes, and materialized views. Critical Concepts: Expect in-depth questions on Chebotko diagrams, the nuances of primary, partition, and clustering keys, and how they influence data distribution and access patterns. Understanding multi-row partitions and the implications of adding clustering keys is vital. CQL Operations: Beyond basic CRUD, the exam covers "upserts" with INSERT or UPDATE, their behavior in applied/unapplied batches, and as lightweight transactions (LWT). Advanced Techniques: Knowledge of read/write techniques, including lightweight transactions, batches, secondary indexes, and materialized views – when and how to use them effectively. Data Types: Specific focus on date/time vs. timestamp, and UUID vs. TIMEUUID. Schema Elements: Understanding the STATIC keyword and its implications. Consistency & Replication: Scenarios involving replication factor (RF) per data center and read/write operations with specific consistency levels (CL), including linearizable consistency. Unexpected but Important Topics (as per QuickTechie.com): DSBulk: A powerful utility for data loading/unloading/counting, often featured in exam questions. ERD Notations: A refresh on Entity-Relationship conceptual modeling from RDBMS may be beneficial. Hybrid/Multi-Cloud Deployments: Some questions may touch upon modern deployment strategies. Topics Less Emphasized (as per QuickTechie.com): While foundational, the exam tends to focus less on generic NoSQL vs. RDBMS comparisons, DataStax Enterprise (DSE) specific features, internal architectural components like compaction, read repair, snitch, hinted handoff, NodeSync, or detailed read/write path internals. The Exam Experience: What to Expect The DataStax Cassandra Certification is an online proctored examination, available 24/7 for your convenience. QuickTechie.com provides valuable insights into the process: Logistics: You'll need a valid photo ID (driver's license or passport), a machine with a webcam, microphone, flash enabled, and stable internet. The proctor will verify your identity and environment. Format: The exam consists of 60 single-select multiple-choice questions, to be completed within 90 minutes. There are no True/False or multiple-select questions. Difficulty: The exam is moderately difficult, requiring thorough preparation or practical experience. Many questions are scenario-based, testing problem-solving skills. Scoring: A passing score of 70% is required. There is no negative marking, so it's advisable to attempt all questions.

Build a scalable, fault-tolerant and highly available data layer for your applications using Apache Cassandra About This Book Install Cassandra and set up multi-node clusters Design rich schemas that capture the relationships between different data types Master the advanced features available in Cassandra 3.x through a step-by-step tutorial and build a scalable, high performance database layer Who This Book Is For If you are a NoSQL developer and new to Apache Cassandra who wants to learn its common as well as not-so-common features, this book is for you. Alternatively, a developer wanting to enter the world of NoSQL will find this book useful. It does not assume any prior experience in coding or any framework. What You Will Learn Install Cassandra Create keyspaces and tables with multiple clustering columns to organize related data Use secondary indexes and materialized views to avoid denormalization of data Effortlessly handle concurrent updates with collection columns Ensure data integrity with lightweight transactions and logged batches Understand eventual consistency and use the right consistency level for your situation Understand data distribution with Cassandra Develop simple application using Java driver and implement application-level optimizations In Detail Cassandra is a distributed database that stands out thanks to its robust feature set and intuitive interface, while providing high availability and scalability of a distributed data store. This book will introduce you to the rich feature set offered by Cassandra, and empower you to create and manage a highly scalable, performant and fault-tolerant database layer. The book starts by explaining the new features implemented in Cassandra 3.x and get you set up with Cassandra. Then you'll walk through data modeling in Cassandra and the rich feature set available to design a flexible schema. Next you'll learn to create tables with composite partition keys, collections and user-defined types and get to know different methods to avoid denormalization of data. You will then proceed to create user-defined functions and aggregates in Cassandra. Then, you will set up a multi node cluster and see how the dynamics of Cassandra change with it. Finally, you will implement some application-level optimizations using a Java client. By the end of this book, you'll be fully equipped to build powerful, scalable Cassandra database layers for your applications. Style and approach This book takes a step-by- step approach to give you basic to intermediate knowledge of Apache Cassandra. Every concept is explained in depth, and is supplemented with practical examples when required.
