Ah, sorry, I meant Perfetto solely as an example of related library and not
something that we had actually evaluated. Thanks for the details on the use
cases.
I think the PR should be ready now, and then we can start instrumenting the
engine/Flight and seeing how we can best make use of this. T
Hmm, I see the mention but I don't recall actually working with
Perfetto (though, it's entirely possible I did and just forgot). My
goal isn't entirely identifying code bottlenecks however. I'd divide
it into two:
Improving Arrow's C++ engine: OT is very helpful here, especially when
working on
Ah, right - I'm not suggesting we use Perfetto, rather I'm just generally
curious about people's experience with these kinds of tools.

A quick update on this, I don't think this will happen for 5.0; the upstream
library still hasn't reached 1.0, and I don't want to cram this in at the end

upstream fix in order to keep all our CI platforms working. Furtherm
I just updated the PR with support for exporting to Jaeger[1], which
has a built in trace viewer.
1. Download and run the all-in-one Jaeger binary locally[2] (or their
Docker image)
2. Build Arrow with `-DARROW_WITH_OPENTELEMETRY=ON -DARROW_THRIFT=ON`
3. Run your application with `env ARROW_TRA
I'll have to do some more digging into that and get back to you. So
far I've been using a quick-and-dirty tool that I whipped up using

FWIW, I tried this out yesterday since I was profiling the execution
of the async API reader. It worked great so +1 from me on that basis.
I did struggle finding a good simple visualization tool. Do you have
any good recommendations on that front?

I agree that OpenTelemetry is the future; I have been following the
observability space off and on and I knew about OpenTracing; I just realized
that OpenTelemetry is its successor. [1]
I have found tracing to be a very powerful approach; at one point, I did a POC
of a trace recorder inside a Ja
Hi David,
I'm favorable to adopting a tracing library.
My main question is: does integrating OpenTracing complicate our build
procedure? Is it header-only as long as you use the no-op tracer? Or
do you have to build it and link with it nonetheless? The
opentracing-cpp documentations seem
I agree that having arrow flight play well with open telemetry based
observability systems would be great (and the future).
It seems to me it would be fairly implementation dependent -- so each

Dear David,
OpenTelemetry tracing is definitely the future, I guess the question is how far
down the stack we want to put it. I think it would be useful for flight and
other higher level modules, and for DataFusion for example it would be really
useful.
As for being alpha, I don’t think it
Hello,
For Arrow Datasets, I've been working to instrument the scanner to find
bottlenecks. For example, here's a demo comparing the current async
scanner, which doesn't truly read asynchronously, to one that does; it
should be fairly evident where the bottleneck is:
