<![CDATA[Mixed database table types (MyISAM vs InnoDB)]]>Hello. I noticed in looking at the databases of various websites (trying to cleanup some old plugin data) that I have a mixture of MyISAM and InnoDB table types. Some are MyISAM type and some are InnoDB type.

I assume they should all be InnoDB as I tried deploying a fresh instance of WordPress and used PHPMyAdmin to verify that they are all InnoDB by default, so I am presuming I should be converting the MyISAM to InnoDB.

Any thoughts on how to fix this all to InnoDB? Is this something I should just ignore? My concern is this may be an issue down the road and so if I can be proactive then I'd rather be proactive.

Screenshots below...

Older install (notice the mix of InnoDB and MyISAM types):

Fresh install (notice the InnoDB is the type used for all tables):

It’s definitely odd and I’m surprised I only recently discovered this concern. Some of them definitely existed before Cloudron days and came over as part of the “all in one migration” plugin which I have a feeling overwrite the database to match the original source, so likely is part of the reason there. Some newer ones also have it though but thinking further I think it’s because it was an issue in the template one I spun up new site builds from.

I’ll try converting and hopefully that’ll help with some stuff. Will report back on whether it’s successful or not 🙂

I would suggest converting. Atleast, all our tests in the MySQL addon assume InnoDB and never tested with MyISAM.

MyISAM

afaik, MyISAM is sort of obsolete. We only support InnoDB since the beginning. Was the initial WP installation from Cloudron ?

TBH, I didn't even know one could mix tables this way!
