[hibernate-dev] Performance issues with HT_ tables?

Sorry to ask for help on the dev list but it seems as if no regular user would ever have to deal with such low level issues. Since we're having serious performance problems (queries running more than an hour...) with HT_ tables I was looking for documentation that describes the when/why/how/etc. of temporary tables. It can't seem to find anything online or in the Hibernate books. All I find at http://www.google.com/search?q=hibernate%20%22HT_%22 are unanswered forum questions or dead JIRA entries. It'd be nice if one of the developers could point me into the right direction. -> Problem: https://forum.hibernate.org/viewtopic.php?f=1&t=1008637 Regards, Marcel -- Marcel Stör, http://www.frightanic.com Couchsurfing: http://www.couchsurfing.com/people/marcelstoer O< ascii ribbon campaign - stop html mail - www.asciiribbon.org
