Hey everyone, For Iceberg we're using UUIDs in Avro and we're storing them as binary, rather than a string. This has several advantages such as more compact storage, more efficient reading, and more efficient skipping. For more details, please check out the doc that I've created <https://docs.google.com/document/d/16_oSWrEM7AFUCTe0uuraAEHxywezLfoEz5ahzwvhGUk/edit#heading=h.43xuauwfk7ow> (and feel free to comment). Also created AVRO-3918 <https://issues.apache.org/jira/browse/AVRO-3918> on Jira to track this.
Looking forward to hearing from y'all! Kind regards and happy holidays, Fokko Driesprong
