> When a table is declared as write-once/append-only (IMMUTABLE_ROWS=true), then we should disable the conflict detection being done by Tephra as there can be no conflicts. This is a much lighter weight model that relies on Tephra mainly to:
> - filter rows for failed (and unabortable) transactions.
> - not show transactional data until it has successfully been committed.
