Hi all,

Each broker has it's own instance of a SequenceManager. This means that each
time a broker is created, a new SequenceManager is created; the
SequenceManagerHiLoImpl
does a grab of n ids when it is created. This means that two brokers,
pointing to the same PBKey (i.e. database) will not be producing contiguous
IDs. I attach a testcase with two tests illustrating this issue.

This is not a huge issue, but one I think should be resolved at some point
in the near future. My immediate gut feeling is that there should be one
instance of SequenceManger created per PBKey, but I'm open to other
approaches. Essentially, I don't want to be "wasting" ids unnessarily, but I
also want the performance benefits of the HiLo generation algorithm -  in
other words, I don't mind skipping IDs when a server app is restarted, but
I'd rather keep them contigous during a run.

Cheers,

Charles
