The primary key for replies was shifted away from UUID as this does not scale well for b-tree indexing. A composite PK for this table makes the most sense from a normalization standpoint, however, the amount of complexity is not really worth it so the decision was made that with the 16 million amount of possible tickets with 4.2 billion possible replies which averages to around 256 replies per ticket which seems like a very reasonable average on the total amount of estimated replies per ticket.
