Subject [jira] [Commented] (KAFKA-689) Can't append to a topic/partition that does not already exist
Date Thu, 10 Jan 2013 10:10:15 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-689?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13549500#comment-13549500

ben fleis commented on KAFKA-689:

Although it's not precisely the same, perhaps thinking about topic|partition as a remote file
open is a useful metaphor.  An open() call is where you would set normal open params (flush
interval, O_CREAT, etc.), and stat() is where you get broker and other real time updates.
 Of course, if create is explicit, where does delete come into play?

@Jun - I don't see where in server.properties anything about topic creation exists?  And further,
does an extra RPC matter if it's only during setup/periodic?

> With a totally fresh Kafka (empty logs dir and empty ZK), if I send a ProduceRequest
for a new topic, Kafka responds with "kafka.common.UnknownTopicOrPartitionException: Topic
test partition 0 doesn't exist on 0". This is when sending a ProduceRequest over the network
(from Python, in this case).
> If I use the console producer it works fine (topic and partition get created). If I then
send the same payload from before over the network, it works.
