David Li commented on ARROW-15756:
----------------------------------
I couldn't get this to work. I wonder if UCX_TLS=self only works if both sides
share a worker as well (which would be a little unfortunate).
> [C++][FlightRPC] Benchmark in-process Flight performance
> ---------------------------------------------------------

> Key: ARROW-15756
> URL: https://issues.apache.org/jira/browse/ARROW-15756
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: David Li
> Assignee: David Li
> Priority: Major
>
> It can be convenient to use Flight to abstract over communication within a
> process and between two processes. We should add this case to the benchmark
> to start. UCX has an in-process loopback transport ({{UCX_TLS=self}}), and
> ARROW-15282 will enable implementing a specialized transport if more
> performance is desired (e.g. possibly based on the C Data Interface).
