It seems that as of today, I think, MySQL 4 is now going to be available in two flavors, Pro and Classic. The Pro version will have transaction support, while Classic is a “version optimized for raw speed without transactions.” It took me a few minutes to find explinations of each, here’s their product information page.
I run a version that has txn support is this somehow going to be taken away so I will have to rewrite certain critical code that’s implemented with transactions and do all the locking myself?
