> Parquet logical type UUID fails on read.  Only workaround is to store as text, a 225% penalty. 
> Here is the schema dump for the attached test parquet file.  I can read the file okay from R and natively through C++.
> {code:java}
> 3961 $ parquet-dump-schema uuid.parquet
> required group field_id=0 schema {
>  required fixed_len_byte_array(16) field_id=1 uuid_req1 (UUID);
>  optional fixed_len_byte_array(16) field_id=2 uuid_opt1 (UUID);
>  required fixed_len_byte_array(16) field_id=3 uuid_req2 (UUID);
> }{code}
> I'm new.. I put this as MAJOR from reading the severity definitions, but gladly defer to those who know better how to classify.
