From f792dd74e1e6f64cb15d920d87818f47f17e7848 Mon Sep 17 00:00:00 2001 From: Sean Quah <8349537+squahtx@users.noreply.github.com> Date: Mon, 28 Nov 2022 13:42:06 +0000 Subject: Remove option to skip locking of tables during emulated upserts (#14469) To perform an emulated upsert into a table safely, we must either: * lock the table, * be the only writer upserting into the table * or rely on another unique index being present. When the 2nd or 3rd cases were applicable, we previously avoided locking the table as an optimization. However, as seen in #14406, it is easy to slip up when adding new schema deltas and corrupt the database. The only time we lock when performing emulated upserts is while waiting for background updates on postgres. On sqlite, we do no locking at all. Let's remove the option to skip locking tables, so that we don't shoot ourselves in the foot again.
