Hi! I'm working on debugging a problem with how message timestamps are handled in the sarama client. In some cases, the sarama client won't associate a timestamp with a message while the kafka console consumer does. I've found the documentation on the message format here:
https://kafka.apache.org/documentation/#messageformat But the information there is very sparse. For instance, what are 'firstTimestamp' and 'maxTimestamp'? It seems that when I'm debugging sarama, firstTimestamp is set to -1 and maxTimestamp appears to be the timestamp I want. Is there some state about the message that I need to understand in order to have maxTimestamp be used? Any further documentation or guidance on this would be very helpful! On another note, I am trying to debug this through the scala/java console consumer, but I'm having a hard time getting IntelliJ setup. Is there anything special or documentation I need to set this up for debugging?
