The demand for Apache Cassandra™ and NoSQL skills is skyrocketing, with Cassandra developers commanding 31% higher salaries, the highest of any database technology.
An Apache Cassandra™ Administrator Associate Certification, Apache Cassandra™ Developer Associate Certification, or Apache Cassandra™ K8ssandra Associate Certification is the best way to get started learning and mastering the popular NoSQL database used by teams at Apple, Netflix, Sony, Uber, and thousands more.
An official certification helps you gain confidence in your knowledge of Apache Cassandra™ and increases opportunities for career advancement.
The Developer Certification is designed for professionals that use Apache Cassandra clusters to manage data. This includes roles such as application developers, data architects, database designers, and database administrators.
The Administrator Certification is designed for professionals who install, configure, manage and tune the performance of Apache Cassandra clusters, such as database administrators, DevOps engineers and Site Reliability Engineers (SREs).
The K8ssandra Certification is designed to up-level your DBA know-how to SRE skills. The topics covered in this exam include Docker, basic Kubernetes constructs, Sidecar, secrets, port-forwarding, helm, ingress, storage, Reaper repair, Medusa backup, K8ssandra, the cass-operator, Prometheus metrics collection, and Grafana metrics display.
Follow a Learning Path to gain an expert understanding of Apache Cassandra™ and DataStax Enterprise principles related to your role.
Each Learning Path is composed of a sequence of recommended courses for your role, curated by our Curriculum Engineers. Courses assume a basic familiarity with programming concepts, the Unix/Linux command line, and networking and storage principles.
In preparation for taking the certification exam, we have created a set of lessons in this Learning Series which contains all the information required to pass the exam. Each lesson comes complete with Kubernetes and Docker fundamentals workshop videos, DataStax product documentation, and hands-on exercises to reinforce course content. These courses assume you have a basic knowledge of CQL, Data Modeling, and Query optimization.
Ring, nodes, replication and consistency, and how Cassandra achieves scalability, availability, performance, fast response time, and low latency
Cassandra Query Language (CQL) operations including, INSERT, UPDATE, DELETE, and SELECT, and tools for bulk loading and unloading
Conceptual, logical and physical data models, plus schema definition including keyspaces, tables, columns, partitions, clustering columns, user defined types, collections, secondary indexes, and materialized views
Installing Cassandra tarball, YAML configuration file options including vnodes, seeds, gossip, snitches, JVM Tuning, and security (authentication, authorization, and encryption),
