FYI, I've done a bit of reading about Aria engine (my knowledge about it to-date was mainly based on conversations with Monty). It seems to me that Aria is probably not yet ready for serious use, based on https://mariadb.com/kb/en/aria-faq/: * goal for current version: "keep the code stable and fix all found bugs." * next version is "on hold as the developers are focusing their main efforts on improving MariaDB" * ultimate goal is "to be a MyISAM replacement. This is possible because Aria can also be run in non-transactional mode, supports the same row formats as MyISAM, and supports or will support all major features of MyISAM." At the same time https://mariadb.com/kb/en/myisam-storage-engine/ says "You're encouraged to rather use the Aria storage engine for new applications, which has even better performance and the goal of being crash-safe." I am going to run some tests with Aria. I'll keep you posted what the conclusions are.
