What you'll learn

Level: Beginner

Modern transactional applications require a distributed SQL database that maintains resiliency and performance at scale. For this reason YugabyteDB created a distributed database with an extensible API called YCQL. Yugabyte Cloud Query Language, or YCQL,  is a semi-relational SQL API compatible with the Cassandra Query Language.

In the first course, YugabyteDB Development Fundamentals, you learned about how to use the YCQL APIs Data Definition Language and Data Manipulation Language to create and manipulate keyspaces and tables.

In this course, you will learn how to gain performance and reduce latency by using query-first data model design principles. You will also learn about query planning and query optimization tuning using secondary indexes. You will also learn about advanced data types, user defined data types, and built-in functions. 


Wanted: Administrator, Developers, Architects, and Business Users

This course is ideal for folks who have already taken the YugabyteDB YCQL Development Fundamentals course. You should already be familiar with YugabyteDB concepts, terminology, and features. Additional experience with semi-relational data model, SQL, and Bash shell scripting is helpful.
