----------------------------------
Summary: [Format] UUID type
Key: ARROW-2152
URL: https://issues.apache.org/jira/browse/ARROW-2152
Project: Apache Arrow
Issue Type: Improvement
Components: Format
Reporter: Uwe L. Korn
Add a UUID type that is physically represented as an 128bit fixed sized binary.
The addition of the type should add the annotation that a value in this column
is a UUID. The important benefit would be that in the native language object
models we could return the respective UUID class, e.g. {{java.util.UUID}} in
Java and {{uuid.UUID}} in Python. For reference, Postgres and Parquet both have
a UUID type as well do other data system have this small specialization.
