# ==== Purpose ====
#
# This test will generate a random workload on the server mixing SBR and RBR
# on same transaction using SAVEPOINT and ROLLBACK TO SAVEPOINT statements to
# truncate the binlog cache in a certain point of the transaction and will
# assert that all generated transactions have the correct transaction
# "rbr_only" flag on GTID events.
#
# ==== Related Bugs and Worklogs ====
#
# BUG#25040331: INTERLEAVED XA TRANSACTIONS MAY DEADLOCK SLAVE APPLIER WITH
# REPEATABLE READ
