On my to-do list is to write a paper that explains why fine-grain locking is not practical without either (1) a dedicated server process to manage the locks or (2) enhancements to OS locking primitives that are not currently available on any OS that I am aware of. There is a widely held belief that since OSes provide byte-level locking of files it should be a simple matter to provide row-level locking in a serverless database engine. The proposed paper will explain why that belief is incorrect. D.
