# #
# Testcase for worklog WL#5743: Lift the limit of index key prefixes #
# Accorrding to WL#5743 - prefix index limit is increased from 767 #
# to 3072 for innodb. This change is applicable with Barracuda file #
# format. #
# All sub-test in this file focus on prefix index along with other #
# operations #
# #
# #
# Creation: #
# 2011-05-19 Implemented this test as part of WL#5743 #
