In fact, from your own team at Facebook: - DROP/ALTER table was slow. Fast implementation in 5.5 didn't make it to 5.6, fixed - GTID implementation in production is hard to do in 5.6 (I understand facebook-5.6 has some solution around this possibly) - http://bugs.mysql.com/bug.php?id=70265 - http://bugs.mysql.com/bug.php?id=68220 (maybe not a bug, but a behavioural oddity) - https://www.facebook.com/notes/mysql-at-facebook/eq_range_index_dive_limit-system-variable-in-mysql-56/10151533648715933 (maybe even you wrote this? One can't tell from the FB note) There's a longer list in Yoshinori's excellent talk on MySQL 5.6 at Facebook. I hope those slides make it online somewhere/sometime And given that I also have no experience with something like Oracle, I have no idea if their new releases are any better either or take a similar amount of time to stabalize I see you have commented on the blog post, I look forward to the discussion there as well. cheers, -colin [1] - What maybe is not clear overall are the reasons as to why some features in MariaDB are being re-written. I see some good documentation in an example like https://mariadb.atlassian.net/browse/MDEV-452 but this is not always the case as to why there is reasoning for a decision (some are probably in commit logs, some are probably discussed on IRC, etc.) -- Colin Charles, Chief Evangelist MariaDB | t: +6-012-204-3201 | Skype: colincharles _______________________________________________ Mailing list: https://launchpad.net/~maria-discuss Post to : [email protected] Unsubscribe : https://launchpad.net/~maria-discuss More help : https://help.launchpad.net/ListHelp
