Subject: Speeding up schema changes
Date: Mon, 3 Sep 2007 13:22:15 +0200
Message-ID: <adf34c300709030422p7a5bf9ban915c01547c3cb008@mail.gmail.com> (raw)

Is there a way to speed up simple schema changes like ...

 ALTER TABLE foo ADD COLUMN bar CHAR(64);

... where foo already contains millions of records?

On a live database changes like this can take hours. Even when the
database is idle.

Is there a better way to do this?

 S.
