> Hi,
> We are using kafka stream to consume messages from one kafka topic.
> Due to some business logic, we ignore all the packets before 8am by returning {{-1L}} from {{CustomTimestampExtractor}} for all such packets.
> We start consuming all the packets after 8am.
> Everything is running fine, but consumer lag on my consumer group before 8am keeps increasing and goes to 0 after 8am.
> {{{}[commit.interval.ms|http://commit.interval.ms/]{}}}{{{}=1000{}}} commit interval is set to 1s
