-------------------------------------
Hi,
I have tested it again and my results are:
When storing an object, a temp file is created for most databases to find out
how long the binary object is. For databases that support
PreparedStatement.setBinaryStream with unknown size (currently only the H2
database), no temp file is created.
When retrieving an object (prop.getStream()), the call sequence is: 1)
DbDataStore.getRecord(..), which calls touch(..) but touch(..) returns quickly.
2) DbDataRecord.getStream(), which calls touch(..) but touch also doesn't do
anything. Here a temp file is created, otherwise the connection would be
blocked until the application read the blob. By the way, after running the
test, I did not have any leftover temp files.
So if I run the test, everything looks fine to me.
