Re: Number of tables in a DB

The limit is "big". For MyISAM, you might think about table opening and closing overhead, since the 3 files for each table are stored in one directory. Easy to end up with lots of file opening overhead on some operating systems and/or file systems.

Why do you want lots of tables?

Are you thinking of more than 100,000 per database? More than 10,000? If only 100 or 1,000 then don't even think of worrying about it, except with Windows FAT partitions. Even there, setting the table cache value large enough will make it insignificant.
