Madhusudan C.S. commented on KAFKA-566:
---------------------------------------
Makes sense, I will see if I can implement them. Btw, do we already have
getMetadataRequest call implemented? I looked it up and I could not find it. Or
does TopicMetadataRequest translates to getMetadataRequest for clients?
> Add last modified time to the TopicMetadataRequest

> Key: KAFKA-566
> URL: https://issues.apache.org/jira/browse/KAFKA-566
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.8
> Reporter: Jay Kreps
> Priority: Blocker
> Fix For: 0.8
>
>
> To support KAFKA-560 it would be nice to have a last modified time in the
> TopicMetadataRequest. This would be the timestamp of the last append to the
> log as taken from stat on the final log segment.
> Implementation would involve
> 1. Adding a new field to TopicMetadataRequest
> 2. Adding a method Log.lastModified: Long to get the last modified time from
> a log
> This timestamp would, of course, be subject to error in the event that the
> file was touched without modification, but I think that is actually okay
> since it provides a manual way to avoid gc'ing a topic that you know you
> will want.
> It is debatable whether this should go in 0.8. It would be nice to add the
> field to the metadata request, at least, as that change should be easy and
> would avoid needing to bump the version in the future.
