    Description

      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.
