############## mysql-test\t\transaction_write_set_extraction_basic.test##################
# #
# This test checks the basics of setting the variable transaction_write_set_extraction #
# #
# Variable Name: transaction_write_set_extraction #
# Scope: GLOBAL | SESSION #
# Access Type: Dynamic #
# Data Type: enum #
# Default Value: OFF #
# Allowed value: OFF / MURMUR32 / XXHASH64 or 0 / 1 / 2 #
# #
# Description: Test Cases of Dynamic System Variable transaction_write_set_extraction #
# that checks the behavior of this variable in the following ways #
# * Default Value #
# * Valid & Invalid values #
# #
# This test also verifies : #
# #
# 1. The server option transaction_write_set_extraction cannot be modified #
# inside a multi-statement transaction. #
# #
# 2. The new server option transaction_write_set_extraction can only be set #
# when the binlog format is ROW and fails with other binlog formats. #
# #
# Note: This var cannot be set also when Group Replication is running. #
# This test is done in the group replication suite #
