Hello guys,
I have one monster database running on MySQL 4.0.17, using InnoDB:
270GB Oct 10 14:35 ibdata1

I've deleted a lot of register of then, and I've expected that the size
can be decreased if 50% (135 GB) but the ibdata was the same value than
before "clean"...
How can I force to save this space?

You must dump your data to files,

Why not change the table type to MyISAM instead of dumping to a file?

If you have a bunch of indexes on the table, you're creating the indexes on the MyISAM table too. It could be a lot more expensive than a dump and restore.

Otherwise it sounds like a good idea.
