Those tables are used as part of bulk update/delete HQL processing
Thank you. That much I figured by now ;-)
However, this does not explain (for me) why
a) Why they are used at all in the situation I described - are they used
for all bulk update/delete HQL operations regardless of context/mapping
strategy?
b) Why the update in my situation runs for more than an hour. That's an
absolute disaster because all other transaction fail with lock timeout.

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.
