# === Purpose ===
#
# This test verifies that ORDER BY on replication pfs tables returns
# the correct data set.
#
# === Implementation ===
#
# 1) Setup a multi-source replication topology.
# 2) With STS, execute DDLs on both the masters and use SQL ordering
#    on PFS tables on slave.
# 3) Repeat step 2 with Multi-threaded Slave.

#                ASSERTION)
