Dan Berindei commented on ISPN-3937:
------------------------------------
We need to also look at the other tricks Hibernate uses in its SpecializedMySqlStringCacheStore: http://pastebin.com/4w0mAf65
E.g. there is another issue to use REPLACE INTO for MySQL: https://issues.jboss.org/browse/ISPN-686
