--- Comment #1 from Brion Vibber <[email protected]> 2011-09-09 23:14:21 UTC --- tl;dr summary: This Online Schema Change tool is a PHP script which manages cloning a table, applying an ALTER TABLE, and then swapping it back in place. This runs online -- not interfering with live operations on the main tables -- by using triggers to capture changes made to the original table while the new table is being changed. Note that in a replicated environment, you need to run this on all slaves before running on the master -- but unlike our prior schema update methods, it doesn't require halting replication while running, or switching masters. Sounds pretty spiffy! -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
