From c9bca8c5e0d31d7c844c8e9c96588d0c7c5e0392 Mon Sep 17 00:00:00 2001 From: zeripath Date: Thu, 19 Aug 2021 05:11:36 +0100 Subject: [PATCH] Recreate Tables should Recreate indexes on MySQL (#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.
