I have an issue with a very very large site that had been running MU, and then upgraded to 3.0.
Looking at the database, The core WP tables are all in MyISAM.
However, the individual user blogs — all _thousands_ of them, are using a combination of MyISAM and InnoDB
The specific breakdown is like so (across all user blogs):
wp_1048_bad_behavior MyISAM //plugin wp_1048_commentmeta MyISAM wp_1048_comments InnoDB wp_1048_links InnoDB wp_1048_options InnoDB wp_1048_postmeta InnoDB wp_1048_posts InnoDB wp_1048_term_relationships MyISAM wp_1048_term_taxonomy MyISAM wp_1048_terms MyISAM
Ive scoured the old MU code, and know enough about stand alone WP, so Im not seeing where the cause of this would be anything other than a server configuration change, mysql upgrade, etc.. — (i dont think WP did this)
Does anyone else? has anyone else seen this?
Secondly, does anyone see a reason why the InnoDB tables couldnt be converted over to MyIsam? Or vice-versa?
As it stands, using both is causing quite the load on the MySQL cluster.
Thanks in advance for any insights.
