Ismael Juma created KAFKA-4336:
----------------------------------

             Summary: Frequent log rolling when there's a mix of delayed and 
current data
                 Key: KAFKA-4336
                 URL: https://issues.apache.org/jira/browse/KAFKA-4336
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 0.10.1.0
            Reporter: Ismael Juma
             Fix For: 0.10.2.0


Jun said in KAFKA-4099: suppose that you have 2 producers, one producing data 
with the current timestamp and another producing data with timestamp 7 days old 
(e.g., if some data is delayed or some old data is replayed), this will still 
cause the log segments to roll frequently. This may not be common, but can 
definitely happen. So, it seems we will still need to improve on how log rolls.

I am creating a new JIRA because KAFKA-4099 is closed so easy to lose track.
