# ==== Purpose ====
#
# Clear variables that were persisted with SET PERSIST[_ONLY]
# For now it only resets single primary variables
#  - group_replication_single_primary_mode
#  - group_replication_enforce_update_everywhere_checks

# ==== Usage ====
#

# Clean persisted primary mode options on all servers to avoid contamination
# to other testcases.
