Native Data Types

In Cassandra’s data modeling process, the physical data model Chebotko diagram incorporates column data types for each table. The diagram is included below for reference. This lesson focuses on Cassandra’s data types.

Apache Cassandra data types 

Apache Cassandra is not a schema-less database. It requires the data type for each column to be specified in the table definition. This helps validate and restrain the data coming in. The data type dictates how the data is stored on disk, impacting the speed at which it is read and also helps sort data in the correct order.

In this lesson, we will look at the native CQL data types.
