**课程名称:** Cassandra Essentials: NoSQL 分布式数据开发 **课程概述:** 本课程深入介绍 Apache Cassandra，一款广泛应用于关键任务负载的强大且流行的 NoSQL 数据库。课程将带您超越关系型数据库的基础知识，揭示 Cassandra 的环形架构和容错设计如何消除性能瓶颈和单点故障。您将学习如何在多个节点甚至跨不同数据中心复制数据，从而确保在硬件或网络发生中断时，您的应用程序仍能保持在线。 通过理论讲解和实践演示，您将掌握 Cassandra 的数据建模最佳实践，包括使用分区键、簇集列和反规范化来创建专门针对高速写入和大规模读取的模式。您还将了解 Cassandra 如何通过可调一致性来平衡性能和数据准确性，让您在每次查询时都能控制数据的“新旧”程度。此外，您还将学习 TimeUUIDs、集合和二级索引等实用功能在实际用例中的应用。 **课程目标:** 学完本课程后，您将具备设置 Cassandra 集群、构建数据模型以及自信地执行 CQL 查询的技能。无论您是构建拥有数百万用户的全球性应用程序，还是希望更深入地理解分布式数据库，本课程都将为您提供在下一个项目中驾驭 Cassandra 的速度、韧性和可扩展性所需的知识和实践经验。
Dive into the world of Apache Cassandra-one of the most powerful and popular NoSQL databases trusted by tech giants for mission-critical workloads. This course takes you beyond the basics of relational databases, unveiling how Cassandra's ring-based architecture and fault-tolerant design eliminate bottlenecks and single points of failure. You'll explore how to replicate data across multiple nodes-and even across different data centers-so your applications can stay online even when hardware or network disruptions occur.Through a blend of theory and hands-on demonstrations, you'll master Cassandra's data modeling best practices-using partition keys, clustering columns, and denormalization to create schemas perfectly tailored for high-speed writes and large-scale reads. You'll also learn how Cassandra balances performance and correctness with tunable consistency, giving you control over just how "up-to-date" your data needs to be in any given query. And you'll see how practical features like TimeUUIDs, collections, and secondary indexes fit into real-world use cases.By the end of the course, you'll have the skills to set up your own Cassandra cluster, craft your data models, and confidently run CQL queries. Whether you're building a global application with millions of users or simply want a deeper understanding of distributed databases, this course will equip you with the knowledge and hands-on experience to harness Cassandra's speed, resilience, and scalability in your next project.
