----------------------------------
Summary: Add UUID logical type
Key: PARQUET-1125
URL: https://issues.apache.org/jira/browse/PARQUET-1125
Project: Parquet
Issue Type: Task
Components: parquet-format
Reporter: Ryan Blue
I think we should add a UUID logical type that is stored in a 16-byte fixed.
The common string representation is 36 bytes instead of the 16 required. UUIDs
are commonly used as unique identifiers, so it makes sense to have a good
support. A binary representation will reduce memory when writing or building
bloom filters and will reduce cycles needed to compare values.
