> The Kafka client has the ability to start consuming at an offset before or after a given point in time. The granularity of this offset is the log file as the Kafka servers do not keep track of arrival time of various messages.
> This means that the granularity of offsets relative to time depends on arrival rate of messages and thus of log file rotation. A topic with lots of messages will have its log files rotated very often (thus each spans a short time interval) whereas a topic with very few messages might not see its log files rotated for hours.
> In order to circumvent this granularity disparity, having a parameter that would force log file rotation after a certain delay (xxx ms) would allow for pretty much constant time granularity to be available at the cost of more file descriptor being used.
