Not necessarily ... if you are using a filesystem in which directory
lookups in large directories are inefficient, you could have a problem,
since each table will correspond to a file within the database
directory. If you're planning on having more than a few thousand
tables you'll want to choose a filesystem that copes well with large
But having said that, an application that needs several thousand
distinct tables is usually an application that needs a redesign.
Consider folding the data into fewer tables with more key columns.
