Following on from our earlier announcement, Paul McCullagh has responded with the answers to your questions - as well as a few I gathered from other Percona folks, and attendees of OpenSQL Camp. Thank you Paul!
What’s the "ideal" use case for the PBXT engine, and how does it compare in performance? When would I use PBXT instead of a storage engine like MyISAM, InnoDB or XtraDB?
