thanks for the example.  It seems like providing some sort of
temporary table which is not logged would also help those applications.
I think derby already does this if the temp tables are single user -
single transaction, but no multi-user cross transaction temp table support.

Unlogged multi-user temporary tables might be interesting.  I believe
there is a SQL standard in this area.  Anyone know what other db's do
in this area?

From responses to Dan's original post on building a system with the
sync options disabled it seemed like there was enough response that
those options should be made available.  I admit I am worried because
this system can no longer guarantee recoverability.  It would be
interesting to know how people would use such a configuration.

I agree with you that a database system without recoverability is useless.


One use for a database without recoverability is for data
warehousing/reporting.

The database used as a datamart needs to be created without error but once
created the core tables can be read-only. Other read/write tables will be
used for searches, match-engine results and temporary tables to support
report-ready processes. Loss of data in these tables would not be serious
since they start out empty at the start of a process anyway.
