Daniel, innodb data files keep growing as needed, it even be of 20Gb

I was under the impression that you should avoid files > 2GB on 32 bit systems, which have to do some dodgy stuff to support files bigger than 2GB. Does this advice apply?

If you want several data files (mainly because performance)
you need to add them in the my.cnf following the instructions in:

14.2.7. Adding and Removing InnoDB Data and Log Files
http://dev.mysql.com/doc/refman/5.0/en/adding-and-removing.html

Yeah I've been reading that. It says that if we have an autoextend file ( which we do ), then it's current size ( around 500MB now ) will be the limit for all subsequent autoextend files. I'd like to be able to set a limit of 1

That's not how I read it.  How did you draw this conclusion?


OK. Upon 2nd reading, it seems like I was wrong. The size of the current autoextend file only affects the final size of *that* ibdata file; not subsequent ones. So therefore I can do something like:

innodb_data_file_path = ibdata1:512M;ibdata2:1024M;ibdata3:1024M;ibdata4:1024M

... all the way to 30 of them :)
