# ==== Implementation ====
#
# This test will create a workload and will block the table to be written
# on the slave to force the SQL thread or slave worker to wait.
#
# Then, this test case will query P_S tables to ensure that a slave worker
# thread if MTS is enabled, or the SQL thread for STS that is considered a
# worker too, is waiting.
