# WL#6737:  InnoDB: Enabling InnoDB temp-tables as default internal SE for
#	    MySQL Optimizer
#

--source include/no_valgrind_without_big.inc

# There are expected differences in explain output when run with and without
# binary logging. Thus, test is updated to run with binary logging ON.
# Testcase is skipped for binlog_format=MIXED and STATEMENT, since it mismatches
# result file for used_columns output (Bug#22472365).
--source include/have_binlog_format_row.inc

# Optimizer plan are printed as part of the test-case and changing page
# size will affect the optimizer plan numbers. so enable it only for 16K
