#
# This file should be included from tests for MW-369 to run concurrent
# transaction from node_1 with autocommit query from node_2.
#
# The parameters:
# * $mw_369_parent_query - the parent query to be run inside transaction
# * $mw_369_child_query - the child query
#
# The operations are the following:
#
# node_1:
# START TRANSACTION;
# $mw_369_parent_query
# node_2
# $mw_369_child_query - will be blocked on node_1 in apply monitor
# node_1:
# COMMIT;             - will be blocked on node_1 in local monitor
#
# The $mw_369_child_query is always expected to succeed. The caller is
# responsible for checking if the final COMMIT on connection node_1
# succeeds.
#
