# MDEV-24327 wsrep XID checkpointing order violation with log_slave_updates=OFF
#
# Here we have configure two node cluster with --log-bin=ON and --log-slave_-updates=OFF
#
# a transaction in node executes so far that it has replicated and reached
# commit phase, We have sync point before entering commit order monitor and
# the transaction is parked there
#
# Then another transaction is executed in node 2, it replicates and commits in node 2
# and is received and applied in node 1. After applying it will remain waiting for
# commit order monitor, as it has later seqno than the first transaction in node 1.
#
# control connection in node 1 waits to see the
#
# With the buggy version of MDEV-24327, the applier has however, already synced the
# wsrep XID checkpoint
