################################################################################
# The aim of this test is to verify that Group Replication successfully
# blocks DML's on non-transactional tables.
#
# 0. Start a server with Group Replication
# 1. Create tables with different storage engines, this should not be blocked
# (INNODB, CSV, MyISAM, MEMORY, ARCHIVE, BLACKHOLE, MRG_MyISAM)
# 2. Perform DML's on non-transactional tables, the instructions should FAIL.
# 3. Execute a DML(INSERT..SELECT) on innodb table where select is from
# non-transactional table. The instruction should FAIL.
# 4. Alter the non-transactional table's engine to INNODB and execute
# DML(INSERT..SELECT) again. This time instruction should SUCCEED.
# 5. Clean-up
