Q

Only UDP

On page 475 of your book, (second edition) you talk about network transmission errors causing transaction reordering when a database uses a file system for its storage. Is it correct to say that this would occur if only using UDP, and not TCP?

Thanks!


Yes, you are right. TCP should prevent transmissions from being delivered out of order. This was an oversight on my part in the book. I plead guilty in buying into the FUD factor on this one.
