Hive Data Types and Transformation Data Types

Hive Data Types and Transformation Data Types

The following table lists the Hive data types that Data Integration Service supports and the corresponding transformation data types:
Hive Data Type
Transformation Data Type
Range and Description
Binary
Binary
1 to 104,857,600 bytes. You can read and write data of Binary data type in a Hadoop environment. You can use the user-defined functions to transform the binary data type.
Tiny Int
Integer
-32,768 to 32,767
Integer
Integer
-2,147,483,648 to 2,147,483,647 Precision 10, scale 0
Bigint
Bigint
-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 Precision 19, scale 0
Decimal
Decimal
For transformations that support precision up to 38 digits, the precision is 1 to 38 digits, and the scale is 0 to 38.
For transformations that support precision up to 28 digits, the precision is 1 to 28 digits, and the scale is 0 to 28.
If a mapping is not enabled for high precision, the Data Integration Service converts all decimal values to double values.
If a mapping is enabled for high precision, the Data Integration Service converts decimal values with precision greater than 38 digits to double values.
