Max tables in a MySQL database

Question

Is it bad to have too many tables in a database? I have about 160 tables in one database. Is it better to split it into several database rather than using a single database? Sin

Answer 1

There are no server limits on the number of tables in a MySQL database. You will definitely have no problems with 160 tables, and you don't need to split them into multiple databases.

You will not gain performance by splitting your tables into multiple databases. If performance remains an issue, you could consider using per-table tablespaces in order to place some sets of tables on different physical disks.
