From c369e956918333c19cfb21def41c8a54f9d09c90 Mon Sep 17 00:00:00 2001 From: Patrick Cloke Date: Thu, 8 Dec 2022 11:40:20 -0500 Subject: [PATCH] Rebuild the user directory and stats tables. (#14643) Due to the various fixes to the StreamChangeCache it is not safe to trust the information in the user directory or room/user stats tables. Rebuild them as background jobs. In particular see da777207528513c858395758bf4c023da2c2c1a3 (#14639), and 6a8310f3dfe77acf59df2fe3e88a71b85b9b3ecc (#14435).
