# ==== Purpose ====
|
|
#
|
|
# Test verifies that replicated transaction boundaries are set properly
|
|
# at receiving from master time.
|
|
#
|
|
# ==== Implementation ====
|
|
#
|
|
# A. Simulate an unnoticeable loss of Xid event to observe a slave error,
|
|
# then restart slave to recover from the failure.
|
|
# B. Do the same to GTID event.
|
|
#
|
|
# ==== References ====
|
|
#
|
|
# MDEV-27697 slave must recognize incomplete replication event group
