The WordPress revisions stores a record of each saved draft or published update. Whenever you save a page or post in WordPress it creates a revision. Revisions can be helpful in case you need to revert back to a previous version of your content. WordPress is written smart enough to ignore revisions while rendering the front end and its MySQL queries are written well enough so revisions don’t actually slow them down.

Revisions are practically full copies of your posts, so if you have hundreds of posts this means you have few hundreds revisions stored too.
There is only ever a maximum of one autosave per user for any given post. New autosaves overwrite old autosaves. This means that no, your tables do not grow by one row every 60 seconds. In multi-user settings, one autosave is stored for each user.

In fact, whether your power goes out, your browser crashes, or you lose your internet connection, when you go back to edit that post, WP will toss up a warning telling you that it has a backup of your post and a link to restore the backup.
