Remove beam logging in playground for Python

[hjtran]

I get a lot of complaints about all the logging in Beam playground for python examples. It really drowns out any output that might be coming from the examples.

I attempted to just remove the logging altogether for the python examples here, though I have no way of testing it.

My rationale is that the Beam playground environment doesn't really make sense to have logging for. If something goes wrong with an example, it makes a lot more sense to just copy and paste the example into your local Beam environment and debug it there (and optionally turn on logging in your own environment).

@liferoad - Who might be a good person to review this change.

My 2 cents: To be honest, I am not sure what is a good change here. People use playground to learn, and logs help learning. But too much logging does not really help with learning.

@hjtran could you provide some examples to show the logging issue here?

[volatilemolotov]

@hjtran @liferoad Yeah examples would be good. I agree with @aaltay on this one as logging does show some internals and could be valuable for learning the SDK. Especially if results are usually at the end of stdout and you can easily scroll to the end

Hey all, thanks for the reviews!

Here's an example with AggregationSum

The results of this example are taken from the Apache Beam Playground cache.

• The first INFO message it's not really even clear which transform is causing this.
• The second message is a bit distracting imo since I don't think you can even use a different runner in Playground and the user is likely here just to learn about combiners.
• The first warning message is again imo a bit distracting as the likely user probably isn't interested in this interactive visualization from beam
• The second warning message is again not relevant
• The final INFO message is hard for a user to even know what it's referring to The final logged "55" is what actually relates to the example, but it is dwarfed by the irrelevant messages that come before it. I've gotten feedback that it's hard to tell that there's any output related to the example.

I've been using Playground as a way to teach people the Beam model and abstractions and I think this kind of logging makes it a lot harder to do that.

@hjtran we do not have a way to control the logging levels now with Playground. With your PR, it will remove all the logs.

[hjtran]

@liferoad we could adjust the levels like the way #25692 does.

I think it'd be an improvement to adjust to ERROR, but I'd still argue that these logging messages don't help with the goal of learning with Playground so we may as well remove them.

[liferoad]

Can we at least adjust this PR to ERROR? I think it is needed if users play with the wrong code.

Changed!

https://github.com/apache/beam/actions/runs/11451588425/job/31878797880?pr=32740 I tried twice but both failed.

Any guess as to why the "Operation was canceled"? I'm not sure how to troubleshoot this

Does this run locally? :playground:backend:runLint

[robertwb]

FWIW, I totally agree that these logs are quite unhelpful, regardless of if you're in the playground or not.

[hjtran]

How do I retrigger the precommit here? Looks like @volatilemolotov fixed the issue that caused the cancellation of the precommit runs

Run Playground PreCommit

[volatilemolotov]

@hjtran It will not be able to trigger by comment now as the PR is before my updates. Easiest way is to just add a new commit and push to re-trigger.

Bump @liferoad (note, I'm away from computer for the month of November after today)
