What are cassandra collections?

In Apache Cassandra, collections are a way to store and group data within a table column, offering three main types: sets (unordered, unique values), lists (ordered, potentially non-unique values), and maps (key-value pairs).

Sets store a collection of unique values of the same data type in an unordered manner.

Lists store a collection of values of the same data type in a specific order, allowing for duplicate values.

Maps store a collection of key-value pairs, where each key is unique and both keys and values have associated data types.
