# ==== Purpose ====
#
# This test verifies that when binlog_row_image=minimum and a table has
# both unique + primary key then there should not be any conflict running
# the transactions on this table on the soure and replica.
#
# ==== Requirements ====
# R1. In case of binlog_row_image=minimum, when generating read_sets and
# writesets, we should include unique key also such that transaction dependencies
# are calculated correctly and transactions do not fail on replica while running
# in parallel.
#
# ==== Implementation ====
#
# 1) Create source-replica topology.
# 2) Save the current variable values.
#    2.1) Save current binlog_row_image.
#    2.2) Save current tracking mode and extraction algorithm.
# 3) Setup neccesary variables on source.
#    3.1) Set the binlog_row_image to MINIMAL on source.
#    3.2) Set the global transaction extraction algorithm to XXHASH64
#         and the tracking mode to WRITESET.
# 4) Create table and procedure on source.
# 5) Switch to source and call procedure.
# 6) Clear system variables on source.
# 7) Cleanup.
