# ==== Purpose ====
#
# This test case will check if DMLs inside XA transactions are
# considered unsafe when using SBR and are being binary logged using
# RBR when mixed binary log format is used.
#
# The Step 1 covers the unsafe warnings for SBR by forcing statement
# based replication for a single XA transaction.
#
# The Step 2 covers the logging as RBR case by generating a workload
# that would produce a deadlock on the slave applier if applied using
# statements.
#
# ==== Related Bugs and Worklogs ====
#
# Bug#25786490 XA TRANSACTIONS ARE 'UNSAFE' FOR RPL USING SBR
#

# This test case should only run in mixed mode replication.
