# INSERT on dup key update is replication unsafe
# There can be three case
# 1. 2 unique key, Replication is unsafe.
# 2. 2 unique key , with one auto increment key, Safe to replicate because Innodb will acquire gap lock
# 3. n no of unique keys (n>1) but insert is only in 1 unique key
# 4. 2 unique key , with one auto increment key(but user gives auto inc value), unsafe to replicate
# Case 1
