From 92243f1306c9ae54b7b86059017412e230310792 Mon Sep 17 00:00:00 2001 From: ThibG Date: Wed, 23 Dec 2020 16:43:11 +0100 Subject: [PATCH] Fix mentions not being deleted efficiently (#15416) As a regression from the recent optimizations, mentions were left untouched until `account.destroy`, which would then delete them individually, and executing queries to find and delete associated notifications, resulting in a massive slowdown.
