On Saturday July 22, 2023… the SysOp of Lemmy.ca got so frustrated with constant overload crashes they cloned their PostgreSQL database and ran AUTO_EXPLAIN on it. They found 1675 rows being written to disk (missive I/O, PostgreSQL WAL activity) for every single UPDATE SQL to a comment/post. They shared details on Github and the PostgreSQL TRIGGER that Lemmy 0.18.2 and earlier had was scrutinized.
No. Care to explain please?
