That is not what I state. If 2 rows are inserted on two different DB
server and one needs to be updated because of these two inserts, this
might run into a lock on the update of this one for each insert.

Deadlocks can occur even with a _single_ server and no clustering,
unless you are running with transaction isolation level set to
"serializable", which comes with a massive performance penalty (it will
give you write concurrency of 1, i.e. as bad as MyISAM).
