Pig Data Types
Pig Data Types: It includes the data types of pig and how they handle concepts such as missing data.
It also helps us to explain the data to a pig.
The data types of Pig can be divided into two categories:
- Scalar Data Types
- Complex Data Types
Scalar Data Types
Pig scalar types are simple types that appear in most programming languages.
| Data Types | Description | Example |
| Int | It is a singed 32-bit integer value | 2 |
| long | It is a singed 64-bit integer value | 15L or 15I |
| Float | It is a 32-bit floating point value | 4.5F or 4.5.5f or 4.5e2f or 4.5E2F |
| double | It is a 64-bit floating point value | 08.5 or 08.5e2 or 08.5E2 |
| Boolean | Boolean represents true or false values | true/false |
| charArray | It is a Character array | Hello tutorialandexample |
| byteArray | The default datatype in pig is a ByteArray | |
| bigInteger | It displays the BigInteger | 70204096223145 |
| bigDecimal | It displays the BigDecimal | 198.789654123133211 |
Complex Data Types
Pig has several complex data types, such as tuples, bags, and maps. All of these types contain data of each type, including other complex types. It is therefore possible to have a map where the value field is a bag containing a tuple. Here, one of the fields is a map.
| Data Types | Description | Example |
| Map | It has Key and value pair data | [websitename# tutorialandexample.com] |
| Tuple | It’s a collection of one or more fields | (12,56) |
| Bag | It is a collection of one or more tuples | {(12,56),(54,78)} |
