Thanks! yes we got to that conclusion. The question came from Radim in Infinispan team attempting to figure out how to squeeze some more performance from the JPACacheStore from Infinispan.
It's tricky that in Infinipan we don't know if something is a new entry or an update; I had a highly customized MySQL CacheStore which used the "INSERT OR UPDATE" statement, a non-standard feature from that DB which is very useful for this case. Could be interesting for Hibernate ORM to think of a JPA merge implementation which could take advantage of such custom extensions? Requires quite a different Dialect API.
