#
# Stress the storage engine with rapid CREATE/DROP TABLE/INDEX
# and following SELECT/INSERT/SHOW etc.
# Subtest 8 variants (8A - 8D)
#
# The variables
#     $loop_size -- number of rounds till we look at the clock again
#     $runtime   -- rough intended runtime per subtest variant
#     $engine_type -- storage engine to be used in CREATE TABLE
# must be set within the routine sourcing this script.
#
# Other stuff which must already exist:
# - connection con2
# - stmt_start and stmt_break prepared by the default connection
#
# Please look for more details within include/ddl1.inc.
