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 or Apache Cassandra™ Developer 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).
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.
Ring, nodes, replication and consistency, and how Cassandra achieves scalability, availability, performance, fast response time, and low latency.
