-# TEMPORARY mitigation for https://bugs.mysql.com/bug.php?id=116741 (incorrect query
-# results when an in-memory temp table spills to an on-disk InnoDB temp table).
-# Fixed upstream in MySQL 8.4.11; remove once Percona XtraDB Cluster ships a v8.4.11-based
-# release (PXC typically lags upstream MySQL by 1-2 months) and revert to the v8.4 default
-# of disabling TempTable mmap (temptable_use_mmap=off), since both variables are deprecated
-# and slated for removal in MySQL 9.7.
-#
-# Deliberately hardcoded rather than exposed as new job properties: this is a short-lived
-# workaround, not a feature, and it can already be overridden per-deployment via the
-# existing engine_config.additional_raw_entries mechanism if needed.
-#
-# Note: on 8.4, temptable_max_mmap has no effect unless temptable_use_mmap is also on -
-# the "modern equivalent" framing in MySQL docs only applies starting in 9.7.
