Learn about Apache Cassandra and its key scalable and reliable data management features.

cassandra.tar.gz

Apache Cassandra is an open-source, distributed NoSQL database recognized for its scalability, reliability, and continuous availability. The course explores the core concepts that drive these features, including distributed architecture, data modeling, CQL, table design, data types, tunable consistency, and the read/write path. 

Lessons combine theoretical insights with hands-on exercises, allowing you to execute CQL queries directly in your browser and view real-time results with no setup required. Additionally, each module concludes with a quiz to test your understanding of the material. 

By the end of this course, you’ll be equipped with the skills needed to use Cassandra for high-performance data management.

Introduction to Apache Cassandra

columnName TUPLE '<' cql_type (',' cql_type)* '>'

For example to create a tuple capturing the title, first, middle, and last name in one name column, the following statement can be included in table definition:
```
name tuple<text, text, text, text>
```
Similarly the `address` column below is defined as a tuple consisting of five elements representing the different components of an address: street, city, state, postal code, and country.
```
address tuple<text, text, text, int, text>
```

Explore the Tuple data type for compactly grouping related data within a single column, and understand the key differences between Tuples and User-Defined Types (UDTs).
