# Stress the storage engine with rapid CREATE/DROP TABLE/INDEX

# and following SELECT/INSERT/SHOW etc.

# Subtest 2 variants (2A - 2D)

#

# 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.
