There was a problem hiding this comment.
I don't like the idea of operating with the DB inside index?

topics_and_keysis eating about 200 bytes per statement, which is about 30% of the contribution for each statement.Since this structure was need only when we clean up of statement it makes more sense to just read the statement from the database instead of paying such a high memory price for each statement.
