Hey folks With 4.0, we have an opportunity to reset the default values and add constraints in the configurations based on our learnings since 3.0.
Here's a KIP which modifies defaults for some properties and modifies the constraints for a few others. https://cwiki.apache.org/confluence/display/KAFKA/KIP-1030%3A+Change+constraints+and+default+values+for+various+configurations Looking forward for your feedback.
