[QST] What is the best way of handling string UUIDs in Merlin? #1091

Originally posted by **BlakeB415** December 22, 2023 What would be the best way of going about this? I would rather not maintain a separate UUID to Int mapping table. My original idea was to either Hash or Categorify the UUID values for training, then have the ``user_id_raw`` and ``item_id_raw`` string values be returned from the Feast store during inference so that my application can get the raw UUIDs. However, Merlin does not support this paradigm as I get type errors during inference.
