Dear Frens, Thanks for your message.
I’m fully aware that this is a community mailing list, and I’ve always approached it with the intent of constructive discussion and knowledge sharing. Asking for input on technical questions — even briefly — is not out of place in such forums. If every message had to meet arbitrary length or formality standards, participation would likely drop, not improve. As for the line you quoted — “Need inputs for below query. Please share views.” — I don’t see how that’s "unacceptable." It was a concise and polite request, not a demand. If the brevity offended you, that wasn’t the intent — but it’s worth recognizing that tone interpretation is subjective, especially in written communication. Lastly, suggesting that someone is treating the list like a "help desk" just because they asked a question feels unnecessarily harsh. Communities thrive when people feel welcome to engage, not when they’re policed for wording. That said, I’ll certainly continue to be mindful of how my messages are framed.

And I’m going to be a little bit blunt here, but I don’t think you should treat this mailing list as a help desk. You need to realise that this is a community mailing list. Your e-mail ends up in the mailbox of probably hundreds or maybe even thousands of people. I think that you should work on your tone of voice. Something like this is at least to me unacceptable: > Need inputs for below query. Please share views. Also, I think you should improve your questions themselves. You should indicate what do you already know, what you did to answer the question yourself and what documentation was missing. In the case of how Flink handles Kafka partition assignment, have you read the documentation on https://nightlies.apache.org/flink/flink-docs-release-2.0/docs/connectors/datastream/kafka/#behind-the-scene? It even links to some great additional resources.
