I would like to know the most affecting InnoDB pain points the customers/potential customers first refer.
some random first thoughts: * main table space defrag / shrink was mentioned already, even with file-per-table this can still be an issue with large transactions able to blow up undo logs ... even an offline defrag by an external tool that requires mysqld to be shut down first may already be worth it * a more personal pain point: now that FULLTEXT index support is finally there SPATIAL indexes are the last missing MyISAM feature that may keep some tables back from being converted to InnoDB * DATA DIRECTORY / INDEX DIRECTORY support for InnoDB tables (implicitly enabling file-per-table, too) ... right now this CREATE option is just silently ignored, doesn't even throw a warning ... * better insight into undo log utilization, esp. with separate undo tablespace ... * ... -- Hartmut Holzgraefe, Principal Support Engineer (EMEA) SkySQL | http://www.skysql.com/
