# **ALTERs to run:** `alter table revision drop key rev_page_id;` (from https://gerrit.wikimedia.org/r/692630)
# **Where to run those changes:** all.dblist
# **When to run those changes:** At any time
# **If the schema change is backwards compatible:** Yes
# **If the schema change has been tested already on some of the test/beta wikis:** Tested in production. See the ticket.
# **if the data should be made available on the labs replicas and/or dumps:** Does it matter? This table is public AFAIK
Note that given that we have rev_page_time index, this possibly can't be much slower ignoring code and the data and given the data, there shouldn't be any noticeable change.
