Guys, the change I'm currently working on to add VAM to JDBCCacheLoader would need an interface change. I haven't yet finished testing it to make sure that it's certainly more performant. The change is this: org.jboss.cache.marshall.ObjectStreamFactory public ObjectInputStream createObjectInputStream(InputStream in) throws IOException; JavaObjectStreamFactory and JBossObjectStreamFactory would implement it. VAM would add: public Object objectFromInputStream(InputStream is) throws Exception Finally, JDBCCacheLoader would call: Object marshalledNode = getMarshaller().objectFromInputStream(is); passing, InputStream is = rs.getBinaryStream(1); // ResultSet Would you guys be happy for me to include this before finishing with http://jira.jboss.com/jira/browse/JBCACHE-879? Without this methods, I would have to loop through the InputStream to create a byte[] containing this data which would a waste of time.
