#
# The goal of this grammar is to stress test the operation of the HEAP storage engine by:
#
# * Creating numerous tables, populating them rapidly and then dropping them
#
# * Using various DDL statements that cause HEAP tables to be created or manipulated
#
# * Have concurrent operation by using mostly TEMPORARY or connection-specific tables
