################################################################################
# This test verifies that parallel execution of
# SELECT * FROM performance_schema.replication_group_member_stats and
# Group Replication options change are handled properly by the server.
#
# Test:
# 0. The test requires one server: M1
# 1. Bootstrap a group on server1.
# Setup a debug point that will block a future
# SELECT * FROM performance_schema.replication_group_member_stats
# after the plugin_running_lock is acquired.
# 2. Asynchronously execute a query on the table
# performance_schema.replication_group_member_stats
# 3. Change a Group Replication option, it must succeed.
# 4. Resume the query on the table
# performance_schema.replication_group_member_stats
# 5. Clean up.
