Illustration: User-Defined Data Type

Apache Cassandra enables the creation of custom data types, known as User-Defined Types (UDTs), to enhance flexibility and efficiency in data modeling. UDTs group related fields together, allowing complex data structures to be stored within a single column. Each field in a UDT is defined by a name and a data type, which can be a native type, collection, or even another UDT.
