Hi Laurent,
I think at this point it's safe to say the problem is solved. If you wanted
to check it out for yourself, Christian committed the spiffy new ID
generators here:
https://hl7api.svn.sourceforge.net/svnroot/hl7api/trunk/hapi-mvn/hapi-base/src/main/java/ca/uhn/hl7v2/util/idgenerator/.
FileBasedHiLoGenerator is the default, and it is effectively doing a
batch-cache as you suggest.
The next version will probably be numbered 2.1, but it is certainly at
least a few months away. A number of under-the-hood cleanups have been
made, and they will require a fair bit of testing before we trust them
enough to release them publicly. Naturally, you can always build from
source if you wanted to check it out early.
Cheers,
James
