Description
*** This training course was recorded during December 2024 and Early 2025 ***Welcome to this training course, a comprehensive guide to upgrading "Apache Cassandra" clusters with minimal risk and downtime. You will learn best practices for planning, testing and executing upgrades.I have truly enjoyed creating this course, carefully designing each section to make the upgrade process clear, practical and engaging. Upgrading a distributed database like Cassandra may seem complex, but with the right knowledge and approach, it becomes an exciting challenge rather than a daunting task.To successfully make use of the content in this course, you should have working knowledge of Apache Cassandra. You should know what is Apache Cassandra and you should know how to install and configure Apache Cassandra, along with basic administration knowledge.We will discuss the importance of "the Upgrade".Software upgrade typically includes significant improvements, new features, performance enhancements, bug fixes and updated security measures.When performing a database upgrade, its essential to plan carefully to ensure availability and minimize downtime. Cassandra's distributed architecture allows upgrading one node at a time enabling "near zero" downtime.After this training course, you will be able to design a proper plan to upgrade Apache Cassandra clusters for a smooth upgrade experience and seamless operation.It is highly recommended to run one of the supported versions of "Apache Cassandra" in production environments.We will learn, how to "install and configure" three different versions of Java Runtime Environment on a Linux server.Upgrading Cassandra involves several key steps and we will discuss all these upgrade steps in detail.We will discuss and understand the various SStable versions in Cassandra.We will understand the differences in the "minor version upgrade" and the "major version upgrade".We will take an existing Cassandra cluster with version 3.11.8 and we will upgrade it to version 3.11.17 (a minor version upgrade) using "in place" upgrade method.Next, we will take an existing Cassandra cluster with version 3.11.17 and we will upgrade it to version 4.1.7 (a major version upgrade).Similarly, we will take an existing Cassandra cluster with version 4.1.7 and we will upgrade it to version 5.0.2 and make it run with OpenJDK 17.We will enable several new features which are ONLY available in Apache Cassandra release 5.0.By the end of this training course, you will be equipped with the knowledge, best practices and real world insights needed to confidently handle any Apache Cassandra upgrade scenario.Whether its a minor patch or a major version upgrade you will understand the steps, tools and precautions required to execute a smooth and successful upgrade.With this solid foundation you will be ready to troubleshoot challenges, make informed decisions and ensure seamless upgrades with minimal risk and downtime. Rest assured, after this training course you will be more than ready to take on "any Cassandra upgrade" with confidence and clarity.
