Subject RE: set new retention size on the fly
Date Wed, 04 Dec 2013 16:15:39 GMT
Thanks for the clarification. I am just curious about how this works out.
If we can change the retention size with "kafka-topics.sh --alter",
will the new retention size be updated to the servers.properties?
If there is any documentation, that will be great.  Another question
is whether you have any release plan for 0.8.1. Thanks.


Regards,

Libo

Just to clarify. Even though # partition is a config property of a topic, it has to be done
through the add partition admin command. Other topic level config changes can be made through
"kafka-topics.sh --alter" in 0.8.1 (trunk).

Thanks,

Jun
