From bc1fefce873384cdde2fb15f76fe3f375d8129db Mon Sep 17 00:00:00 2001 From: zeripath Date: Sat, 21 Aug 2021 03:17:07 +0100 Subject: [PATCH] Recreate Tables should Recreate indexes on MySQL (#16718) (#16740) Backport #16718 The MySQL indexes are not being renamed at the same time as RENAME table despite the CASCADE. Therefore it is probably better to just recreate the indexes instead.
