Jun Rao commented on KAFKA-70:
------------------------------
Prashanth, thanks for the patch.
I suggest that we enforce retention size > log size and disallow the broker to
start if the rule is violated.
> Introduce retention setting that depends on space

> Key: KAFKA-70
> URL: https://issues.apache.org/jira/browse/KAFKA-70
> Project: Kafka
> Issue Type: New Feature
> Affects Versions: 0.8
> Labels: log, roll
> Attachments: KAFKA-70.patch
>
>
> Currently there is this setting:
> log.retention.hours
> introduce:
> log.retention.size
> Semantic would be, either size is reached or time is reached, oldest messages
> will be deleted.
> This does not break back-ward compatibility and would make the system robust
> under scenarios where message size is not deterministic over time.
