Avro data types

supports only some of the primitive and logical data types that Avro schemas provide.

A primitive data type is a type that allows you to represent a single data value. A logical type is an Avro primitive or complex type with extra attributes to represent a derived type. This topic applies to all target types that support Avro or Parquet output format.

The following table lists the primitive Avro data types that

Primitive data type	Description
INT	32-bit signed integer
LONG	64-bit signed integer
FLOAT	Single precision (32-bit) IEEE 754 floating-point number
DOUBLE	Double precision (64-bit) IEEE 754 floating-point number
BYTES	Sequence of 8-bit unsigned bytes
STRING	Unicode character sequence

The following table lists the logical Avro data types that
