# MDEV-20793 Assertion after certification failure during replay.
|
|
#
|
|
# The test outline:
|
|
# In order to produce certification failure three transactions
|
|
# are needed. One transaction is executing on node_1 and two others
|
|
# on node_2. The first transaction from node_2 BF aborts the transaction
|
|
# on node_1, but does not cause certification conflict. The second
|
|
# transaction from node_2 will cause conflict and the transaction on
|
|
# node_1 fails in certification during replay.
|
