Review comment: I've change it back to reflect what the auto-generated schema produces. The reason we didn't have it match the auto-generated schema was because it copies every byte of the record into the `records` field which could be expensive. If this isn't really a problem, I'll leave it as this. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
