Rok Mihevc updated ARROW-2588:
------------------------------
External issue URL: https://github.com/apache/arrow/issues/18971
> [Plasma] Random unique ids always use the same seed
> ---------------------------------------------------
>
> Key: ARROW-2588
> URL: https://issues.apache.org/jira/browse/ARROW-2588
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++ - Plasma
> Reporter: Antoine Pitrou
> Priority: Major
>
> Following GitHub PR #2039 (resolution to ARROW-2578), the random generator
> for random object ids is now using a constant default seed, meaning all
> processes will generate the same sequence of random ids:
> {code:java}
> $ python -c "from pyarrow import plasma; print(plasma.ObjectID.from_random())"
> ObjectID(d022e7d520f8e938a14e188c47308cfef5fff7f7)
> $ python -c "from pyarrow import plasma; print(plasma.ObjectID.from_random())"
> ObjectID(d022e7d520f8e938a14e188c47308cfef5fff7f7)
> {code}
> As a sidenote, the plasma test suite should ideally test for this.
