I can change it back to a static number, but feeling this might be more realistic. This change is originally motivated by debugging the Kafka Server. I thought some data is trimmed because of the timestamp is too old. But it is not related. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
