> So how do I define this `uuid`? Just like you have defined the field `id, name...`. > And what is it used for? If you don't specify a primary key, Hudi would try to use `uuid` as the primary key and find its definition. Or you can specify a primary key, like your `id` field actively. > Does it mean in `0.10.0` tables **must** have a primaryKey? yes -- This is an automated message from the Apache Git Service.
