Out of curiosity, I noticed you mentioned InnoDB specifically, so I assume that this is likely to be engine-specific? Or would this be something added to the pluggable API that engines could, optionally, implement?


Any engine which can handle multiple instances of itself should be fine for this. Conceptually I know how this would work with Innodb... but that is about it.

Right now we would have to call the plugin_init multiple times for the engine and engines would need to keep their context associated within their own hton (this is why hton is passed to all handlerton methods in 5.1, I had mapped this out years ago). Right now no engine supports this though, and the mechanics of how to do "this catalog gets A, while.." I don't know how to do.

Essentially... virtual hosting in the database. I'd like to see us figure out a context language that was better then what was done for the httpd.conf in Apache (though it is not horrible).

I know Innodb's internals well enough to know how to make it work (same for Archive... though that is no big deal). For PBXT or Falcon? No clue.

Cheers,
