> Both the test and the actual implementation in ObjectStore expect the IDs to

> always the case. The above output is ordered using the ID, and start and end
> timestamps should correlate to this, but they don’t.

> It shows that for the first scheduled query the two nodes use their own
> distinct ID ranges. Gemini theorized, the evidence and the DataNucleus
> documentation supports it, that this could be due to ID pre-allocation. From
> the DataNucleus JDO Mapping Guide (v6.0)
> :[https://www.datanucleus.org/products/accessplatform_6_0/jdo/mapping.html#value_generation]
>
> It looks there are two possible solution:
> - disable pre-allocation
> - order by based on an other property that is deterministic, instead of the
> Id itself (maybe end_time can be a proper candidate)
