It sounds like a good idea to me.

@Jesse how about runners "tracing" the constructed DAG (by Beam) so that
it's clear what the runner actually executed ?
Example:
For the SparkRunner, a ParDo translates to a mapPartitions transformation.
That could provide transparency when debugging/benchmarking pipelines
per-runner.

@Dan before starting with Beam, I'd want to know how much performance I've
giving up by not programming directly to the API.

I think there are lots of excellent one-off performance studies, but I'm
not sure how useful that is to Beam.
From a test infra point of view, I'm wondering more about tracking of
performance over time, identifying regressions, etc.
Google has some tools like PerfKit
<https://github.com/GoogleCloudPlatform/PerfKitBenchmarker> which is
basically a skin on a database + some scripts to load and query data;
but I
don't love it. Do other Apache projects do public, long-term benchmarking
and performance regression testing?

I found data Artisan's benchmarking post

They also shared the code <https://github.com/dataArtisans/performance
.
I
didn't dig in much, but they did a wide range of algorithms. They have
the
native code, so you write the Beam code and check against the native
performance.

Hi Jason,I have been busy bench-marking Flink Cluster (Spark next)
under
Beam.I can share my experience. Can you list items of interest to
know
so I
can answer them to the best of my knowledge.Cheers

Subject: Exploring Performance Testing
Hey all,
Now that we've covered some of the initial ground with regard to
correctness testing, I'm going to be starting work on performance
testing
and benchmarking. I wanted to reach out and see what people's
experiences
have been with performance testing and benchmarking
frameworks, particularly in other Apache projects. Anyone have any
experience or thoughts?
Best,
Jason
