Kafka retry commit async on fail - why should I do so?

I use commit async with kafka (obviously without auto-commit).



Unfortunately, I came across the following exception:



error org.apache.kafka.clients.consumer.RetriableCommitFailedException: Offset commit failed with a retriable exception. You should retry committing the latest consumed offsets



After some investigation, I found out that even without committing offsets, the consumer keep on consuming messages from the topic.



After reading a little I saw that it is recommended to retry committing the offsets.



I don't understand why. The consumer is not threadsafe, therefore it is safe to assume that the retry already contains new offsets. And if so, wouldn't next commitAsync attempt suffice?

  • It'll keep consuming, but if the consumer restarts, then you'll re-process uncommitted offsets

What visual should I use to simply compare current year value vs last year in Power BI desktop

Image
0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?

Is there other way than using something like: with pytest.warns(UserWarning): ...
