Look at Monty's keynote slide #12: it calls the feature clearly "Partitioned Key Cache" (see http://en.oreilly.com/mysql2010/public/schedule/detail/12443) BTW, the slides were prepared NOT by me.

Mikael R did not call his new functionality for partition tables at all because what he just lifted one of the limitations of his original implementation: each MyISAM partition was a regular MyISAM table, but not quite. In particular indexes of this table could not be assigned to non-default key caches. So Mikael lifted this limitation. He did not have to touch the key cache code at all. > > In any case, it is not the intent to change anything in the code, > except I guess we need to syncronize the name of the feature with the > user visible variable names. > > henrik _______________________________________________ Mailing list: https://launchpad.net/~maria-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~maria-developers More help : https://help.launchpad.net/ListHelp
