Hi,
I had a look at this and can not figure out why -1 is returned.
When running the kernel in normal (write) mode the return value of
number of ids in use will only be correct if all previous shutdowns
have executed cleanly. This is an optimization to reduce the time
spent in recovery rebuilding id generators after a crash/non clean
shutdown.
After a crash/non clean shutdown the number of ids in use will always
be the highest id in use + 1. To force a full rebuild of the id
generators on each startup (on a non clean shutdown) pass in the
following configuration:
rebuild_idgenerators_fast=false
In read only mode the return value will always be the highest id in use + 1.
You could try to delete the neostore.nodestore.db.id and pass in
"rebuild_idgenerators_fast=false" as configuration when starting up
(this will take a long time if the node store file is large). If you
still get incorrect results send me a compressed version of the
neostore.nodestore.db.id file and I will have a look at it.
Regards,
-Johan
