Micah Whitacre commented on KAFKA-1023: --------------------------------------- Thanks for the feedback. The fact that LogManager was sealed helped to indicate this was not a common integration point. The concern of losing a message due to a consumer being slow or down for a period and the log manager removing messages due to space was what initially inspired looking at it through this approach. Is there by chance a way of alarming/tracking if a log roll is about to occur and not all consumers have an offset higher than the values to be deleted? > Allow Injectable LogManager > --------------------------- > > Key: KAFKA-1023 > URL: https://issues.apache.org/jira/browse/KAFKA-1023 > Project: Kafka > Issue Type: Improvement > Components: core > Reporter: Micah Whitacre > > Currently the LogManager is responsible for deleting and cleaning up messages > based on time or size.
