# MDEV-17614 INSERT on dup key update is replication unsafe
#
# The following cases are tested below:
# 1. 2 unique key, replication is UNSAFE
# 2. 2 unique key, with one auto increment key and implicit value to it.
# It is UNSAFE because autoinc column values of being inserted records
# are revealed dynamically, so unknown at the binlog-format decision time
# and hence this pessimistic expectation
# 3. 2 unique keys
# A. insert is only in 1 unique key, still all colums are specified => UNSAFE
# B. both unique keys are specified => UNSAFE
# C. only one unique key is specified => SAFE (motivated by MDEV-28310)
# 4. 2 unique key, with one auto increment key(but user gives auto inc value) =>
# UNSAFE to replicate
--echo # Case 1: UNSAFE
