BTW, some thoughts about mySQL.

There are some really annoying details:

If you use InnoDB as engine (you should), mySQL generates a ibdata file.

If you delete records/tables, this file does not shrink.

It's getting bigger and bigger and the only way to manage this is to dump the database, drop and recreate it and then loading the dump again.

Ok, one can have a ibdata file for each table. This makes live a little bit easier.

The dump is plain SQL - a text file with tons of INSERT statements.

Loading this dump can last very, very long.

Same thing with backup/recovery.

And you must explicitly backup your grants and stored procedures.

And as far as i know, the only way to force reindexing is the procedure described above.

Many caveats.

And it is a mess to figure out if this all did really work as expected.
